Estimate activity calories from weight, duration, and a known or custom MET value.
Estimated result
Check the entered values.
MET values represent activity averages; intensity, technique, and individual condition change actual expenditure.
MET calculation
kcal/min = MET × 3.5 × body weight kg ÷ 200. Duration turns that rate into an estimated total.
MET and intensity
Each activity uses a local average; custom mode accepts a known MET value.
Frequently asked questions
Will it match a fitness watch?
Not necessarily. Both are estimates using different methods and sensors.
