Calculate how many calories you burn during exercise based on MET values. Supports 50+ activities including running, swimming, cycling, and more. Pure client-side.
This calculator uses MET (Metabolic Equivalent of Task) values to estimate the calories burned during physical activities. MET represents the energy cost of an activity as a multiple of resting metabolic rate. The formula is: Calories = MET × Weight (kg) × Duration (hours). Intensity adjustment: Light ×0.8, Moderate ×1.0, Vigorous ×1.2. All calculations happen in your browser — no data is sent to any server.
MET (Metabolic Equivalent of Task) is a measure of exercise intensity. One MET is your resting metabolic rate (~1 kcal/kg/hour). Running at 8 km/h is about 8 METs, meaning you burn 8 times more calories than at rest.
This calculator provides estimates based on average MET values from scientific research. Actual calories burned vary based on individual factors like age, gender, body composition, and fitness level.
Yes, muscle tissue burns more calories at rest than fat tissue. People with higher muscle mass typically burn more calories during both exercise and rest.
Increase workout intensity, duration, or choose higher-MET activities like running, HIIT, swimming, or jumping rope. Building muscle through strength training also increases your basal metabolic rate.
