The MET formula explained
MET stands for Metabolic Equivalent of Task. One MET equals the oxygen your body consumes sitting still — about 3.5 ml per kilogram of body weight per minute. An activity rated 9.8 METs uses 9.8 times that amount.
Calories burned = Duration (minutes) × (MET × 3.5 × Weight in kg) ÷ 200
Imperial weights are converted to kilograms automatically (1 kg = 2.205 lbs). Intensity scales the MET value: low ×0.75, moderate ×1.0, high ×1.3.
