The calories burned calculator uses MET (Metabolic Equivalent of Task) values to estimate energy expenditure during exercise. MET is the ratio of exercise intensity to resting metabolic rate — a MET of 7 means you burn 7 times more calories than at rest.
Guia passo a passo
- 1Calories burned = MET × weight (kg) × time (hours)
- 2MET values are standardized across activities by the Compendium of Physical Activities
- 3Heavier people burn more calories for the same activity because they carry more mass
- 4Intensity matters: running at 8 mph (MET 13.5) burns 70% more than running at 5 mph (MET 8.3)
