Weight & Rep-Max Conversions

Plates, programs and records come in both pounds and kilograms — 1 kg equals about 2.2046 lbs. This tool converts your weight both ways and, because you entered a rep count, also estimates the one rep max that set represents and projects every rep max from 1 to 10 in both units.
