The equation, in the open

This calculator uses the standard ACSM relationship: kcal per minute = MET × 3.5 × body mass in kg ÷ 200. Multiply by minutes and you have the total. There is no secret model and no adjustment factor — you can reproduce every number on this site with a pocket calculator.

MET values come from the 2024 Adult Compendium of Physical Activities. See how the data is handled for the detail, including where the figures are weakest.
