About this tool
Wondering how much that workout actually burned? This calculator estimates the calories used during exercise from the activity, your body weight and how long you went, using the MET values from the Compendium of Physical Activities.
MET values capture how intense an activity is, so a brisk run scores far higher than gentle yoga. The result is a reliable estimate rather than an exact measurement — fitness and effort change the real number. Everything is computed in your browser.
Frequently asked questions
What is a MET?
A MET (metabolic equivalent) measures an activity's intensity. Calories burned equal MET × your weight in kilograms × the time in hours.
How accurate is it?
It's a solid estimate, but real burn varies with fitness, technique and effort. Treat it as a guide rather than an exact figure.
