Kg to lb converter
This kg to lb converter switches a weight between kilograms and pounds instantly, and also rounds it to the nearest load you can actually put on a barbell in either unit. Enter a value, pick which unit you're converting from, and get the converted number plus the closest loadable weight in kg and lb below it, so you never have to convert plates by hand mid-session.

How it works
The conversion itself is exact: one pound equals 0.45359237 kilograms by international definition, and the calculator applies that factor directly in both directions with no rounding until the final display.
The nearest loadable figures round to 2.5 kg for kilograms and 5 lb for pounds, matching the smallest practical plate jump most gyms load with on each side of the bar, so you get a number you can actually set up rather than a precise but unusable decimal.
The table below is a fixed reference from 20 to 200 kg in 10 kg steps with the pound equivalent alongside, handy for reading off a conversion without typing a value at all.
Frequently asked questions
How many pounds is a kilogram?
One kilogram equals about 2.20462 pounds, so 100 kg converts to roughly 220.5 lb. This calculator applies the exact international conversion factor rather than a rounded approximation, so the numbers stay accurate at any weight, even for oddly specific competition weigh-in targets.
Why does the calculator show a nearest loadable weight?
A converted number like 61.23 kg isn't something you can load exactly with standard plates. Rounding to the nearest 2.5 kg or 5 lb gives you a figure that matches how gyms actually load a bar, so you can go straight from a converted target to a real setup.
Is 45 lb exactly 20 kg?
No, 45 lb is about 20.4 kg, and 20 kg is about 44.1 lb. The two are close but not identical, which is why a program written in pounds and one written in kilograms don't translate perfectly plate for plate.
