Calories Burned Calculator

Estimate calories burned using METs (metabolic equivalents). Results are approximate and vary by individual.

This calculator uses MET values (Metabolic Equivalents of Task) from the Compendium of Physical Activities to estimate energy expenditure. The formula is straightforward: calories burned equals MET value multiplied by body weight in kilograms multiplied by duration in hours. For example, running at 8 km/h has a MET of about 8.3, meaning it burns roughly 8.3 times more energy than sitting at rest. This tool is useful for comparing the calorie cost of different exercises when planning a workout routine, though actual energy expenditure depends on factors like fitness level, terrain, and individual metabolism.
