About this calculator

A calories-burned calculator estimates the energy an activity uses with the MET (Metabolic Equivalent of Task) method. One MET is roughly the energy of sitting still; an activity of 8 METs burns eight times that. Calories per minute = MET × 3.5 × weight(kg) ÷ 200, so heavier people and harder activities burn more.

Frequently asked questions

What is a MET?

A MET (Metabolic Equivalent of Task) is a multiple of your resting energy use. Sitting quietly is 1 MET; a 5-MET activity burns five times as many calories. The values here come from the Compendium of Physical Activities.

How are calories burned calculated?

Calories per minute = MET × 3.5 × body weight in kg ÷ 200, multiplied by the number of minutes. It scales with both how hard the activity is and how much you weigh.

Why does body weight change the result?

Moving a heavier body costs more energy, so the same activity for the same time burns more calories for a heavier person. That is why weight is part of the formula.
