Wilks Calculator

Calculate wilks score. Wilks formula is primarily used in powerlifting contests to identify the best lifter across different weight classes.

!NOTE The formula is tested against real results from WRPF meet.
Works best in metric units. Although there should be no difference if you use imperial units as well.
The result may differ from some websites, but this is because they round to second decimal for all calculations, not just the result. This make the formula less accurate.

🚀 Quick Start

npm i wilks

import { calculateWilks } from "wilks";
// 2020 version
// import { calculateWilks } from "wilks/2020";

// metric units by default
const wilks = calculateWilks("f", 53.2, 352.5); // 431.73
const wilksImperial = calculateWilks("m", 204.6, 2226.6, "imperial") // 635.09

!CAUTION Use the same unit type for bodyweight and total.
