Complete Guide & Formula for Calories Burned Calculator
The MET (Metabolic Equivalent of Task) system is the standard way exercise scientists estimate energy expenditure. Every activity has a MET value representing how many times more energy it burns compared to sitting still. This calculator multiplies the MET value of your chosen activity by your body weight and workout duration to estimate calories burned.
💡 The MET Formula
Calories Burned = MET × weight (kg) × duration (hours).
For example, running at MET 9.8 for 30 minutes at 70 kg burns roughly 343 kcal. Higher-intensity activities have higher MET values, so they burn more calories per minute at the same body weight.
