The formulas federations and platforms actually use
Comparing a 60 kg lifter with a 120 kg lifter, or a light rower with a heavy one, needs a formula — and different organisations use different ones. The IPF has used its GL formula since 2020; many other federations use DOTS; older results and many gyms still quote Wilks. These calculators show all of them side by side with the exact coefficients, so you can see why your numbers differ from one app to another.
Power, not guesswork
For cyclists and rowers, power is the honest measure. The cycling tools turn FTP into training zones for Coggan/TrainingPeaks, Peloton and Zwift, estimate climbing power from physics, and convert VAM to watts per kilogram; the rowing calculator uses Concept2’s own formula linking split and watts, so the numbers match your monitor.
About these calculators
Yes. Every calculator on this site is free to use with no sign-up, and they run entirely in your browser.
The published ones: the IPF’s official GL coefficients (2020), the DOTS polynomial, the original Wilks and Wilks 2020 coefficients, Concept2’s watts formula and weight adjustment, the widely documented Concept2 monitor calorie formula, Coggan’s power zones as published by TrainingPeaks, Peloton’s and Zwift’s zone boundaries, Michele Ferrari’s VAM rule of thumb and the standard physics of cycling power. Each page links to its source.
It should, if you enter the same total and bodyweight and choose the formula your federation uses. Federations round bodyweights and totals in their own ways, so the last decimal can differ — the official result is always the one the federation publishes.
Yes. Enter weights in kilograms or pounds; the formulas themselves use kilograms, and the calculators convert for you.
