Calorie Burn Calculator

Calculate calories burned during exercise. Uses the MET (Metabolic Equivalent) model with 24 common activities, or enter a custom MET value.

Calorie Burn Calculator — Calories burned during exercise depend on three things: your body weight (heavier people burn more), the intensity of the activity (a sprint burns more than a walk), and the duration. The standard model is the Metabolic Equivalent of Task (MET), where 1 MET is the energy cost of sitting quietly, and 5 METs is 5× that cost. The formula is: kcal/min = (MET × 3.5 × bodyWeightKg) / 200.

All math runs locally. No weight or activity data leaves your browser.

Burn estimates use MET averages and are approximations, not medical advice. Actual expenditure varies with body composition, intensity, and conditions. Consult a healthcare professional about exercise decisions.

Calories burned during exercise depend on three things: your body weight (heavier people burn more), the intensity of the activity (a sprint burns more than a walk), and the duration.

The formula is: kcal/min = (MET × 3.5 × bodyWeightKg) / 200.

This tool uses the standard formula with 24 common activities (running, cycling, swimming, yoga, weight lifting, etc.) from the Compendium of Physical Activities (Ainsworth et al., 2000/2011). For unusual activities, enter a custom MET value — most activities fall in the 2-10 MET range.

Cómo usarlo

  1. Enter your body weight

    In kilograms. The formula scales by body weight — heavier people burn more calories for the same activity.

  2. Pick an activity

    24 common activities with accurate MET values. Or enter a custom MET value for an unusual activity (climbing, martial arts, specific sport, etc.).

  3. Enter duration

    In minutes. Most accurate for steady-state activities. For HIIT or interval training, the average intensity is what matters.

Ejemplos

30 min running at 6 mph, 70 kg person

A common cardio session.

Resultado: MET 9.8 × 3.5 × 70 / 200 = 12.0 kcal/min × 30 = 360 kcal

45 min yoga (Hatha), 70 kg person

A lower-intensity session.

Resultado: MET 2.5 × 3.5 × 70 / 200 = 3.1 kcal/min × 45 = 140 kcal
