Calories burned calculator
The calculation uses MET values from the Compendium of Physical Activities: calories = MET × weight in kg × hours. Pick the activity and intensity.
The figure is a population estimate, not a measurement. Individual variation reaches 20–30% depending on movement efficiency and body composition, and wrist heart-rate monitors routinely overestimate effort in strength work.
Frequently asked questions
What is a MET?
A multiple of resting energy use. One MET is the energy you burn sitting quietly; an 8 MET activity burns eight times as much.
Why does a heavier person burn more?
Because they move more mass. At the same speed and duration, energy cost rises almost linearly with body weight.
Is it worth counting calories burned?
As a trend, yes. As an exact number to eat back, no — the estimation error is often larger than the deficit you are trying to create.
