Please note: Loads shown assume plates are added in matching pairs. Always check both ends of the bar before lifting, and use a spotter for heavy work. This calculator is free to use and provided without warranty — see our terms of use.
Deadlift loads comes down to one multiplication. 180 kg is 396.83 lbs, because every kilogram holds 2.20462 pounds and each pound holds 0.453592 kg. The calculator above handles this in either direction, instantly, with no sign-up.

How to Convert deadlift loads in Seconds
You will not need this list twice, but here it is:
- Choose your direction. Leave kg to lbs selected to turn kilograms into pounds, or switch to lbs to kg for the reverse.
- Type the figure. Type the figure as written; no need to tidy it up. Decimals are welcome — 2.75 works exactly as well as 3.
- Press Convert. The result appears underneath with its unit label attached, so there is no guessing which number is which.
Run it as many times as you need. There is no limit and no log.
First, What Are We Converting?
Deadlift milestones are the roundest numbers in strength training and they exist in two incompatible sets. Metric lifters chase 100, 140, 180 and 200 kg. Imperial lifters chase 225, 315, 405 and 495 lbs, which are simply plate counts. Neither set converts into the other neatly, which is why the deadlift generates more conversion questions than any other lift.
A kilogram is the base unit of mass in the metric system, defined since 2019 by the Planck constant rather than a lump of platinum in a Paris vault. A pound — the avoirdupois pound used across the United States and still common in the United Kingdom — is fixed by international agreement at exactly 0.45359237 kilograms. Because both units are pinned to the same agreed definition, converting between kilograms and pounds is exact arithmetic, not an estimate.
There is no sign-up, no paywall and no limit. Type a figure, read the answer, and carry on with whatever brought you here.
The Arithmetic in Full
You never have to write this out yourself, but it helps to see what the tool is doing.
Pounds = Kilograms × 2.20462262185
Kilograms = Pounds × 0.45359237
Take 180 kg. Multiply by 2.20462262185 and you get 396.8321 lbs, which rounds to 396.83 lbs for everyday use. Reverse it: 396.83 lbs × 0.45359237 returns 180 kg. Running lbs to kg to lbs brings you back to your starting figure, which is a quick way to check you have not slipped a decimal place.
The reciprocal relationship matters: 1 ÷ 2.20462262185 = 0.45359237. If a chart gives you numbers that do not reverse cleanly, it has rounded too early.
Common Values at a Glance
Scan the column you need; the arithmetic is already done.
| Kilograms (kg) | Pounds (lbs) | Plate milestone |
|---|---|---|
| 60 kg | 132.28 lbs | 132.28 lbs, bar plus 20 per side |
| 100 kg | 220.46 lbs | 220.46 lbs |
| 102.06 kg | 225 lbs | 225 lbs, two plates a side |
| 140 kg | 308.65 lbs | 308.65 lbs |
| 142.88 kg | 315 lbs | 315 lbs, three plates a side |
| 180 kg | 396.83 lbs | 396.83 lbs |
| 183.7 kg | 404.99 lbs | 405 lbs, four plates a side |
| 220 kg | 485.02 lbs | 485.02 lbs |
Times This Page Earns Its Keep
Readers tell us they use it in situations like these:
- Plate-count thinking. American lifters count plates rather than pounds. Three plates is 315 lbs, which is 142.88 kg.
- Bar height differences. Metric 25 kg plates and imperial 45 lb plates have the same 450 mm diameter, so bar height is unchanged.
- Competition attempts. Meet attempts are declared in kilograms, so a lifter training in pounds converts before the platform.
Two Conversions, Step by Step
The examples below use numbers you might genuinely encounter.
Converting 100 kg
Start with 100 kg. Multiply by 2.20462 and the answer is 220.46 lbs — about 220 pounds in round terms, or 15 st 10.46 lb if you think in stones. In context: 220.46 lbs.
A larger figure: 183.7 kg
Start with 183.7 kg. Multiply by 2.20462 and the answer is 404.99 lbs — about 405 pounds in round terms, or 28 st 12.99 lb if you think in stones. In context: 405 lbs, four plates a side.
Whatever number you start from, the arithmetic is identical.
Small Slips With Big Consequences
Knowing what usually goes wrong is half the battle:
- Rounding too early: Round once, at the end. Rounding at every intermediate step is how a clean calculation quietly becomes a wrong one.
- Confusing pounds with stones: Fourteen pounds make a stone. A reader who reads 11 st 4 lb as 11.4 lb is out by a factor of fourteen, which is a memorable kind of wrong.
- Multiplying when you should divide: It is the single most common error, and it is off by a factor of nearly five. If your answer looks too big, you probably multiplied a pound figure by 2.20462 instead of by 0.453592.
- Trusting 2.2 for large loads: Rounding the factor to 2.2 costs you about 0.2 percent. On 5 kg nobody notices. On 500 kg that is a whole kilogram gone missing.
- Reading a comma as a decimal point: Much of Europe writes 2,5 kg where the UK and US write 2.5 kg. Copying a figure across that boundary without checking is a classic import-paperwork error.
- Assuming a US pound differs from a UK pound: It does not. Since 1959 both are exactly 0.45359237 kg. The confusion usually comes from tons, gallons or fluid ounces, which genuinely do differ.
Written a Dozen Ways, Calculated One Way
A quick detour into wording, because people arrive at this page having typed a remarkable variety of things into a search box.
Common forms include kg into lbs, kgs into lbs, kilo in lbs and kg in pounds. Going the other direction people write lbs to kg, pd to kg, or the frequently mistyped lb to kl. None of these are wrong exactly, and none of them change the answer: 180 kg is 396.83 lbs regardless of how the question was phrased.
The one distinction that genuinely matters is direction, not spelling. Whether you write kg into pounds or kilogram lbs, you are going from metric to imperial and the number gets bigger. Write pd to kg or one pound in kg and you are going the other way, so the number gets smaller. Everything else is presentation.
For what it is worth, the tidiest way to write it in formal documents is kg and lb, lower case, no full stops, with a space between the number and the unit. But nobody will misunderstand you if you write 5kgs into lbs instead.
Mental Maths: Convert Without a Calculator
Halve it for the reverse trip
Going from pounds to kilograms, halve the number and add back about ten percent of the result. 100 lbs → 50, minus 10 percent → 45 kg. True answer: 45.36 kg.
Double and add a fifth
Doubling gets you to 2.0 and you need 2.2, so add a fifth of the original. 180 kg → 360 + 36 = 396 lbs against a true 396.83 lbs.
Good enough for the supermarket. Not good enough for a customs declaration — use the converter for anything that gets written down.
The Agreement That Fixed the Pound
In 1959 six countries signed the International Yard and Pound Agreement and settled something that had been slightly untidy for centuries: exactly how heavy a pound is. The answer they agreed on was 0.45359237 kilograms, and that definition has not been touched since. It is the reason a conversion done in Sydney matches one done in Chicago.
The kilogram itself has had a more eventful time. From 1889 it was defined by a platinum-iridium cylinder kept near Paris, which meant the world's unit of mass was a physical object that could in principle be scratched. In 2019 that changed: the kilogram is now defined through the Planck constant, a fixed number of nature rather than a lump of metal in a safe.
None of this changes the arithmetic you use for deadlift loads, and that is rather the point. A well-chosen definition is one you never have to think about. Multiply by 2.20462262185, or by 0.45359237 going the other way, and the standards infrastructure behind those digits does its work quietly.
If You Are Starting From Pounds
For anyone converting the other way, here are the matching values.
| Pounds (lbs) | Kilograms (kg) |
|---|---|
| 1 lbs | 0.45 kg |
| 5 lbs | 2.27 kg |
| 10 lbs | 4.54 kg |
| 25 lbs | 11.34 kg |
| 50 lbs | 22.68 kg |
| 100 lbs | 45.36 kg |
| 150 lbs | 68.04 kg |
| 200 lbs | 90.72 kg |
| 250 lbs | 113.4 kg |
Getting the Precision Right
The pound is defined as exactly 0.45359237 kilograms. Not approximately — exactly. That means every conversion on this page is a pure multiplication with no measurement uncertainty of its own. Any error in your final figure comes from the number you typed in, not from the maths.
On screen the converter shows two decimal places, because that is what people read comfortably. Behind the display it keeps ten, so if you convert kg into lbs and immediately convert back, you land on your original figure rather than something slightly adrift.
A quick self-test: 100 kg should give 220.46 lbs, and 220.46 lbs should return 100 kg. Any converter that fails that round trip is rounding too early.
Precision in Practice
Gyms are limited by the plates on the rack, not by arithmetic. The smallest common increment is 1.25 kg or 2.5 lb, so any conversion finer than that gets rounded away the moment you load the bar.
The general rule is to carry full precision through the calculation and round once at the very end, to whatever your context genuinely needs. Rounding an input, then rounding an intermediate step, then rounding the answer is how three small and individually defensible decisions add up to a number that is simply wrong.
Two decimals is usually plenty
For almost everything on this page, two decimal places answers the question. 180 kg shows as 396.83 lbs, and the digits beyond that describe a quantity too small to weigh on any equipment you are likely to be using.
When to keep more
Bulk quantities, repeated multiplications and anything that feeds a further calculation all deserve full precision until the last step. The error from early rounding does not stay put — it scales with everything you multiply it by afterwards.
Progress Is a Trend, Not a Session
Converting training loads is straightforward. Interpreting them is where people go wrong, usually by comparing a single good session against another single good session and drawing conclusions from noise.
Loads fluctuate with sleep, food, stress and the simple fact that some days are better than others. What matters is the direction over blocks of weeks, and that trend is unit-agnostic — a 5 percent increase is a 5 percent increase whether you count it in kilograms or pounds.
The practical advantage of metric plates is granularity. A 2.5 kg jump is 5.5 lbs, while the smallest common imperial pair gives 10 lbs. On an isolation movement that difference determines whether progression is possible at all, which is worth knowing before you blame the programme.
Is This Tool Right for You?
This page is written for anyone who needs deadlift loads without a lesson in metrology first. That includes complete beginners: the fields are labelled in plain words and the result is spelled out with its unit attached. Regular users tend to bookmark the chart; occasional users take the number and go. Both are the intended audience.
Why You Can Trust These Figures
Where this page states a real-world figure — a bag size, a limit, a typical weight — it reflects widely published industry norms rather than a single vendor's specification.
Every calculator in our library is tested against known values before publication. For this one that meant checking round numbers in both directions, confirming that a kg to lbs to kg round trip returns the original input, and checking behaviour at the edges — very small decimals, very large loads, and invalid entries.
The conversion factor used here is not our invention. It comes from the International Yard and Pound Agreement of 1959, which fixed the international avoirdupois pound at exactly 0.45359237 kilograms, and it is the same value published by the National Institute of Standards and Technology and the International Bureau of Weights and Measures.
Key Takeaways
- The kg to lbs factor is 2.20462262185. Multiply kilograms by it and you have pounds; 180 kg gives 396.83 lbs.
- Pounds to kilograms uses 0.45359237, an exact defined value rather than a measurement.
- In your head: double the kilograms, add ten percent. Close enough to speak aloud, not close enough to write down.
- Context here: American lifters count plates rather than pounds. Three plates is 315 lbs, which is 142.88 kg.
- Check your work by converting the answer back. Running kg to lbs and then lbs to kg should return your original number exactly.
- Keep full precision until the last step, then round to whatever your situation actually needs.

kg to lbs: The Numbers Worth Memorising
For readers who arrived wanting the raw kg to lbs numbers rather than the background on deadlift loads, this section is for you.
| Value | As kg to lbs | As lbs to kg |
|---|---|---|
| 1 kg | 2.2 lbs | 0.45 kg |
| 2 kg | 4.41 lbs | 0.91 kg |
| 5 kg | 11.02 lbs | 2.27 kg |
| 10 kg | 22.05 lbs | 4.54 kg |
| 20 kg | 44.09 lbs | 9.07 kg |
| 25 kg | 55.12 lbs | 11.34 kg |
| 50 kg | 110.23 lbs | 22.68 kg |
| 75 kg | 165.35 lbs | 34.02 kg |
| 100 kg | 220.46 lbs | 45.36 kg |
Both columns come from the same defined relationship. Because kg to lbs and its reverse are exact reciprocals, any value converted across and back returns to where it started.
For mental work, kg to lbs is double-plus-ten-percent and the reverse is halve-minus-ten-percent. Neither is exact, and both are good enough to catch a mistake before it matters.
The FAQ Section
If your question is not covered above, it is probably here.
What is 405 lbs in kg?
183.70 kg. It is four 45 lb plates per side plus a 45 lb bar, and a well-known strength milestone.
What is a 180 kg deadlift in pounds?
396.83 lbs, which sits just under the 405 lb four-plate benchmark.
Do plate diameters differ between kg and lb plates?
Full-size competition plates in both systems are 450 mm in diameter, so the bar starts at the same height regardless of unit.
What is 60 kg in lbs?
60 kg equals 132.28 lbs. Multiply the kilogram figure by 2.20462 to get there. In context, that is 132.28 lbs, bar plus 20 per side.
What is 100 kg in lbs?
100 kg equals 220.46 lbs. Multiply the kilogram figure by 2.20462 to get there. In context, that is 220.46 lbs.
What is 102.06 kg in lbs?
102.06 kg equals 225 lbs. Multiply the kilogram figure by 2.20462 to get there. In context, that is 225 lbs, two plates a side.
What is 140 kg in lbs?
140 kg equals 308.65 lbs. Multiply the kilogram figure by 2.20462 to get there. In context, that is 308.65 lbs.
What is 142.88 kg in lbs?
142.88 kg equals 315 lbs. Multiply the kilogram figure by 2.20462 to get there. In context, that is 315 lbs, three plates a side.
What is 396.83 lbs in kg?
396.83 lbs comes to 180 kg. Multiply pounds by 0.453592 for the reverse direction — that is the same as saying one pound in kg is 0.453592.
How many grams are in a pound?
453.59237 grams, which is the same defined figure with the decimal point moved.
Where does the conversion factor come from?
The International Yard and Pound Agreement of 1959, which fixed the pound at exactly 0.45359237 kilograms across the English-speaking world.
Do I need to know the formula to use this?
Not at all. The formula is on the page for anyone who wants it, but the calculator does not require you to understand it.
How many ounces in a kilogram?
35.274 ounces. There are 16 ounces to a pound and 2.20462 pounds to a kilogram.
Is mass the same as weight?
Strictly no. Mass is the amount of matter; weight is the force gravity exerts on it. In everyday use the words are interchangeable, and scales are calibrated to report mass.
Can I convert a negative number?
Mass cannot be negative, so the tool asks for a positive figure. If you are working with a difference or a change, convert the magnitude and apply the sign yourself.
Can I convert decimals?
Yes. Type 2.75 or 0.125 or anything else with a decimal point and the tool handles it normally.
What is a metric tonne in pounds?
2204.62 lbs. Note that it is not the same as a US short ton, which is 2000 lbs, or a UK long ton at 2240 lbs.
Can I bookmark or share this page?
Please do. There is no paywall and no registration, so a link works for anyone you send it to.
Does the tool store the numbers I enter?
It does not. The calculation happens in your own browser and nothing is transmitted or saved. Close the tab and the figures are gone.
What is 1 lb in kg?
Exactly 0.45359237 kilograms. That figure is a definition rather than a measurement, which is why it never changes.
What browsers does it work in?
Any current browser on any operating system. It uses standard JavaScript with no unusual requirements.
Can I use it on a phone?
Yes. The layout adapts to small screens and the calculator works the same on a phone as on a desktop.
Is the page updated?
It is reviewed on a rolling basis, and the date at the top reflects the last substantive check. The conversion factor itself has not changed since 1959 and will not.
Why is the kilogram the only base unit with a prefix?
A historical accident. The gram was originally the base unit, but it proved too small to be practical, so the kilogram was adopted while keeping the name.
Is 1 kg exactly 2.2 lbs?
No, though it is close. One kilogram is 2.20462262185 pounds. The 2.2 shorthand is about 0.21 percent low, which is fine in conversation and not fine on paperwork.
How do I convert to stones as well?
Get your pounds figure first, then divide by 14. The whole number is stones and the remainder is the leftover pounds.
Why does my answer differ slightly from another site?
Almost always rounding. A site using 2.2 as the factor will disagree with one using 2.20462262185, and the gap widens as the numbers get larger.
Does the pound differ between countries?
Not the avoirdupois pound. Since 1959 the US, UK, Canada, Australia, New Zealand and South Africa have all used exactly 0.45359237 kg. Tons and gallons are a different story.
How accurate is the conversion?
As accurate as the definition allows. A pound is exactly 0.45359237 kg by international agreement, so the only error possible is in the number you type.
What if my number is very large?
It converts normally. The factor is linear, so a million kilograms converts with exactly the same reliability as one.
Can I convert in both directions?
Yes. The radio buttons above the input switch between kg to lbs and lbs to kg. The rest of the form stays the same.
Does gravity change the conversion?
Not the conversion. Kilograms to pounds is a fixed ratio between two units of mass. Gravity affects what a scale measures, not the arithmetic between units.
Does it work without an internet connection?
Once the page has loaded, yes. The arithmetic is done locally, so you only need a connection to open the page in the first place.
Is there a limit on how many times I can use it?
None. Use it once or a hundred times a day; nothing is counted and nothing is throttled.
What happens if I enter something invalid?
You will get a short message asking for a valid positive number. Nothing breaks and nothing is submitted anywhere.
How does kg to lbs apply here?
The same way it applies anywhere: multiply kilograms by 2.20462262185. Nothing about deadlift loads changes the factor, only which figure you feed into it.
Is the kg to lbs factor different in other countries?
No. Since 1959 the pound has been exactly 0.45359237 kg everywhere it is used, so kg to lbs gives the same answer in every country.
What is the fastest way to do kg to lbs mentally?
Double the kilogram figure and add ten percent of the original. For 60 kg: 120 plus 6 gives 126 lbs, against a true 132.28 lbs. Add another ten percent of the running total to close most of the gap.
What is 15 kg in lbs?
The kg to lbs answer is 33.07 lbs. Multiply 15 by 2.20462262185, or run the kg to lbs step in reverse by multiplying 33.07 lbs by 0.45359237 to return to 15 kg.
What is 35 kg in lbs?
The kg to lbs answer is 77.16 lbs. Multiply 35 by 2.20462262185, or run the kg to lbs step in reverse by multiplying 77.16 lbs by 0.45359237 to return to 35 kg.
What is 45 kg in lbs?
The kg to lbs answer is 99.21 lbs. Multiply 45 by 2.20462262185, or run the kg to lbs step in reverse by multiplying 99.21 lbs by 0.45359237 to return to 45 kg.
What is 55 kg in lbs?
The kg to lbs answer is 121.25 lbs. Multiply 55 by 2.20462262185, or run the kg to lbs step in reverse by multiplying 121.25 lbs by 0.45359237 to return to 55 kg.
In Short
The practical summary for deadlift loads: use the calculator when the number matters, use the double-and-add-ten-percent shortcut when it does not, and keep the units written down either way.
