MET (Metabolic Equivalent of Task) measures how many times more energy an activity uses compared to resting. 1 MET is your resting metabolic rate; running at 8 km/h is around 8-9 METs, so it burns roughly 8-9 times more calories than sitting still.

Why does body weight affect calories burned for the same activity?

Moving more body mass takes more energy, so a heavier person burns more calories doing the same activity for the same duration than a lighter person, even though the MET value for the activity itself doesn't change.

Calories Burned Calculator

Estimate calories burned during an activity based on MET value, weight, and duration.

How this is calculated

Calories = MET × 3.5 × weight(kg) ÷ 200 × duration(minutes)

Assumptions used in this calculation

MET values: MET values are population averages from the Compendium of Physical Activities; actual burn varies with intensity and individual metabolism.

About this calculator

The calories burned calculator estimates energy expenditure for common activities using MET (Metabolic Equivalent of Task) values from the Compendium of Physical Activities, combined with body weight and duration.

Worked example

Walking, 70 kg, 30 minutes

Result: ≈ 129 kcal burned
