How calories burned is calculated

This calculator uses the standard MET (Metabolic Equivalent of Task) formula: Calories = MET × weight (kg) × time (hours). MET values come from the Compendium of Physical Activities. Results are estimates — actual burn depends on fitness level, intensity, terrain, and metabolism. For total daily energy expenditure, try TDEE Calculator. To find your basal metabolic rate, use BMR Calculator.
