Why lifters need both units

Most US gyms load barbells in pounds, but a lot of programming — especially anything sourced from European or Olympic weightlifting coaches — is written in kilograms. This converter handles both directions at once so you're never stuck doing the math mid-set.

It's also the quickest way to sanity-check plate math: a 20 kg bar loaded with 20 kg plates per side is a 100 kg lift, which is roughly 220 lb — useful when a program gives you a kg target and your gym's plates are in pounds.

This is a generic unit converter, and the same kg-to-lb math applies on any other Calcs family site that needs it — the conversion factor (1 kg = 2.20462 lb) doesn't change by sport.

Once your working weight is in the right unit, take it to the plate calculator to see exactly what to load, or the one rep max calculator, bench press calculator, squat max calculator, or deadlift max calculator to work out a target in the first place.

Where these numbers come from

The formulas and default values in this calculator are based on:

  • Standard SI-to-imperial mass conversion (1 kilogram = 2.20462 pounds)

These are planning estimates for training purposes. Check with a coach, trainer, or physician before starting a new program or maxing out.

Frequently asked questions

Why do some programs use kg instead of lb?

Olympic weightlifting and most international strength programming originate from countries using the metric system, so kg is the default unit in a lot of published programs and coaching material.

How much is a standard Olympic barbell in pounds?

A men's Olympic bar is 20 kg, about 44 lb; a women's bar is 15 kg, about 33 lb.

Is the conversion exact or rounded?

The math is exact (1 kg = 2.20462 lb); real-world plate weights are sometimes rounded slightly by manufacturers, so a 45 lb plate isn't exactly 20.412 kg on every set.
