Estimate how many calories you burned during a workout or activity using validated MET (Metabolic Equivalent of Task) values, adjusted for your body weight and workout duration.
Estimate how many calories you burned during a workout or activity using validated MET (Metabolic Equivalent of Task) values, adjusted for your body weight and workout duration. This calculator draws on peer-reviewed, industry-standard formulas used by fitness professionals, dietitians and clinicians worldwide, translated into a fast, easy-to-use browser tool.
Tracking metrics like this over time — rather than relying on a single reading — gives you a much clearer picture of trends in your health and fitness journey. Use this tool regularly alongside our other calculators for a fuller picture of your overall wellbeing.
MET (Metabolic Equivalent of Task) measures the energy cost of an activity relative to resting. 1 MET equals the energy used sitting quietly; running at 10km/h is about 9.8 METs.
Heavier bodies require more energy to move, so calorie burn scales with body weight for the same activity and duration.
These are population-based averages. Actual calorie burn varies with fitness level, terrain, effort, and individual metabolism.
