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.
For CrossFit workout loads, the headline figure is this: 43 kg equals 94.8 lbs. To convert kg to lbs, multiply the kilogram figure by 2.20462; multiply pounds by 0.453592 to come back. The calculator above handles this in either direction, instantly, with no sign-up.
The Short Version
- Best for: benchmark workout comparison and similar everyday situations
- Speed: Instant. The maths happens in your browser the moment you press Convert.
- Rounding: Two decimal places on screen, ten held behind it, so nothing drifts.
- Cost: Free, unlimited, no account, no app to install.
- Works on: Phones, tablets, laptops and desktops, in any modern browser.
How to Use This CrossFit workout loads Converter
Three steps, and the third one is reading:
- 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. Enter it exactly as you have it, with no rounding first. Decimals are welcome — the tool treats 0.125 no differently from 125.
- Press Convert. The result appears underneath with its unit label attached, so there is no guessing which number is which.

So What Does This Page Actually Do?
CrossFit is the clearest example of a sport that never picked a unit. Benchmark workouts are published with both figures side by side because the community is genuinely split: the same workout is 95 lb in one gym and 43 kg in another, and those are not quite the same load. Anyone comparing times across gyms needs to know which.
Kilograms measure mass; pounds, as most people use them day to day, measure the same thing. Physicists will point out that a pound-force is a unit of force rather than mass, and they are right, but on a bathroom scale or a shipping label the distinction does not bite. When you ask for kg into pounds, you want the avoirdupois pound, and that is what this converter gives you.
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 Formula Behind CrossFit kg to lbs
For anyone who likes to check the working, this is it.
Pounds = Kilograms × 2.20462262185
Kilograms = Pounds × 0.45359237
Take 43 kg. Multiply by 2.20462262185 and you get 94.7988 lbs, which rounds to 94.8 lbs for everyday use. Reverse it: 94.8 lbs × 0.45359237 returns 43 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.
Notice that the two factors are exact reciprocals of each other. That is the signature of a properly defined conversion rather than an approximation.

Who Uses This and Why
A few situations that bring people to this page:
- Benchmark workout comparison. Times only compare if the loads match. Convert before you claim a personal record against a published board.
- Scaling loads. Percentage-based scaling works identically in either unit, but the rounding target differs by available plates.
- Kettlebell standards. Kettlebells are sold in kilograms almost everywhere, even in imperial gyms.
From Input to Answer: A Walkthrough
Two examples, worked through completely, so the method is obvious rather than implied.
Converting 15 kg
Start with 15 kg. Multiply by 2.20462 and the answer is 33.07 lbs — about 33 pounds in round terms, or 2 st 5.07 lb if you think in stones. In context: women's bar, 33.07 lbs.
A larger figure: 24 kg
Start with 24 kg. Multiply by 2.20462 and the answer is 52.91 lbs — about 53 pounds in round terms, or 3 st 10.91 lb if you think in stones. In context: the standard men's kettlebell, 52.9 lbs.
The method never changes, only the number you feed it.
Mistakes Worth Avoiding
Watch for these and you will not need to double-check your work:
- 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.
- Mixing up mass and force: Pounds and kilograms both describe mass in everyday use. Pound-force is a different quantity. Unless you are doing engineering statics, you want the avoirdupois pound.
- 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.
- 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.
- 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.
Spelling, Abbreviations and Why They All Mean the Same Thing
One thing worth clearing up before we go further, because it causes more confusion than the arithmetic does: there is no standard way of writing this conversion.
Search boxes see kilograms to pounds, kg into pounds, kilogram lbs, kilo lb and lb kilogram in roughly equal measure. They also see lbs and kg together, as in a request to compare the two, and lbs to kg to lbs, which usually means somebody wants to check their own working by converting a figure and converting it straight back.
Some of the variants are simply typing errors that became common enough to be searched deliberately. Lb to kl is one: there is no unit called a kl in this context, but the k and the l sit next to each other on the way to typing kg. Pd to kg is another, borrowing pd as an informal shorthand for pound.
The practical takeaway: pound and kilogram are the two units, everything else is shorthand, and the converter above accepts your number regardless of what you called the operation on your way here.
Mental Maths: Convert Without a Calculator
Double it, then add ten percent
Take your kilograms, double the figure, then add ten percent of the original. For 43 kg: double is 86, ten percent is 4.3, total 90.3 lbs. The true answer is 94.8 lbs, so you are within about half a percent.
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.
Good enough for the supermarket. Not good enough for a customs declaration — use the converter for anything that gets written down.
Where the Numbers Come From
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 CrossFit workout 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.
The lbs to kg Column
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 |
The Truth About Decimal Places
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.
If you ever want to check the tool, convert a round number one way and then convert the answer back. Landing on your original figure confirms nothing has been rounded away in the middle.
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.
How Much Precision Do You Actually Need?
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. 43 kg shows as 94.8 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 CrossFit workout 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. It is equally useful to people who do this daily and people who will do it once and never again.
How This Page Is Verified
Pages are reviewed on a rolling schedule and the modified date at the top reflects the last substantive check. If you spot something that looks wrong, tell us and we will investigate it rather than leave it.
Our kg to lbs tables are produced programmatically from 2.20462262185, which is why the reverse direction always reconciles exactly.
The reference values in the tables above were computed directly from 2.20462262185, not lifted from a secondary source where a rounding decision had already been made.
The Short Answer, Summarised
- The kg to lbs factor is 2.20462262185. Multiply kilograms by it and you have pounds; 43 kg gives 94.8 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: Times only compare if the loads match. Convert before you claim a personal record against a published board.
- The round-trip test catches nearly every error: convert, convert back, confirm you land where you started.
- Keep full precision until the last step, then round to whatever your situation actually needs.

kg to lbs: The Numbers Worth Memorising
Since this page covers CrossFit workout loads rather than the conversion in isolation, here is a compact kg to lbs reference to sit alongside it.
| 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 |
Read the middle column when your figure is in kilograms and the right-hand column when it is already in pounds. The kg to lbs direction always produces a larger number, which is the quickest sanity check there is.
Where precision counts, use the converter at the top of the page rather than a remembered kg to lbs approximation. Where it does not, the shortcut saves you reaching for a phone.
FAQ: Everything Else You Might Ask
Short answers to the things people ask most.
What is 95 lb in kg for CrossFit?
43.09 kg. Metric gyms typically round the Rx load to 43 kg, which is 94.8 lbs — marginally lighter than the American prescription.
What are standard CrossFit kettlebell weights?
24 kg for men and 16 kg for women in most prescribed workouts, which are 52.9 lbs and 35.3 lbs respectively.
Do CrossFit gyms use kg or lbs?
Both, depending on country. Affiliates in the US mostly use pounds; those elsewhere use kilograms. Official programming often lists both.
What is 20 kg in lbs?
20 kg equals 44.09 lbs. Multiply the kilogram figure by 2.20462 to get there. In context, that is men's bar, 44.09 lbs.
What is 15 kg in lbs?
15 kg equals 33.07 lbs. Multiply the kilogram figure by 2.20462 to get there. In context, that is women's bar, 33.07 lbs.
What is 29.5 kg in lbs?
29.5 kg equals 65.04 lbs. Multiply the kilogram figure by 2.20462 to get there. In context, that is 65 lb Rx load in kg.
What is 34 kg in lbs?
34 kg equals 74.96 lbs. Multiply the kilogram figure by 2.20462 to get there. In context, that is 75 lb Rx load in kg.
What is 43 kg in lbs?
43 kg equals 94.8 lbs. Multiply the kilogram figure by 2.20462 to get there. In context, that is 95 lb Rx load, 94.8 lbs.
What is 94.8 lbs in kg?
94.8 lbs comes to 43 kg. Multiply pounds by 0.453592 for the reverse direction — that is the same as saying one pound in kg is 0.453592.
Does rounding matter?
It depends on scale. Two decimal places is more than enough for a suitcase. For a tonne of freight, rounding the factor rather than the answer can shift the result by several pounds.
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.
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.
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.
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.
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.
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.
What is the fastest mental method?
Double the kilograms and add ten percent of the original. It lands within half a percent, which is close enough for any conversation.
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.
Do I need to install anything?
No. It runs in the browser you are already using. There is no app, no extension and no download.
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.
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.
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.
What browsers does it work in?
Any current browser on any operating system. It uses standard JavaScript with no unusual requirements.
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.
Are lbs and lb both correct?
Both are used and both are understood. Strictly, lb is the abbreviation and lbs adds an English plural to it, but lbs is completely standard in everyday writing.
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 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.
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.
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.
Can I check the tool myself?
Easily. Convert a round number one way, then convert the answer back. If you do not land on your original figure, the tool is rounding carelessly. This one returns it.
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.
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.
How does kg to lbs apply here?
The same way it applies anywhere: multiply kilograms by 2.20462262185. Nothing about CrossFit workout 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.
Wrapping Up
If you take one thing from this page, make it the round-trip check. Convert your figure, convert it back, and confirm you land where you started. It catches almost every error worth catching in CrossFit workout loads.
Anyone needing primary documentation for CrossFit kg to lbs rather than a secondhand account will find it at the NIST Office of Weights and Measures: the NIST Office of Weights and Measures.
