Estimate exercise energy expenditure using MET values for common activities.
Estimate exercise energy expenditure using MET values for common activities.
Enter values above and click Calculate — results will appear here with the formula explained.
Metabolic equivalents (METs) scale energy use against resting metabolism: sitting is 1 MET, so a 9.8-MET activity burns nearly ten times resting rate. The standard conversion turns METs, duration and body mass into calorie estimates used across exercise science.
Estimates carry honest uncertainty. Fitness level, economy of movement and heart-rate realities shift individual results — two runners at identical pace can differ 20%. Use outputs to compare activities and size snacks, not as lab measurements.

Metabolic equivalents (METs) scale energy use against resting metabolism: sitting is 1 MET, so a 9.8-MET activity burns nearly ten times resting rate. The standard conversion turns METs, duration and body mass into calorie estimates used across exercise science. Formula: kcal/min = MET × 3.5 × body-kg ÷ 200; total × minutes
Calories Burned Calculator: Estimate exercise energy expenditure using MET values for common activities. Formula: kcal/min = MET × 3. Example: A 75 kg person running 12.
Estimate exercise energy expenditure using MET values for common activities. Formula: kcal/min = MET × 3.5 × body-kg ÷ 200; total × minutes

A 75 kg person running 12.1 km/h for 45 minutes: 11.8 × 3.5 × 75 ÷ 200 ≈ 15.5 kcal/min → about 696 kcal for the session.
