About this calculator
This is a rough estimate from a simplified speed-to-MET model and the standard MET energy equation. It does not measure your exertion or account for terrain, incline, gait, fitness or individual metabolism; use it as an approximate comparison only.
Worked example
calculated with the default values below
Body weight 70 kg · Time walking 60 min · Walking speed 5 km/h Calories burned 294 kcal · Intensity (MET) 4.0 · Estimated calories per hour 294 kcal/h · Estimated calories per km 59 kcal/km

Formula and variables
MET = min(max(1.5 + 0.5 × v, 2), 8); E = MET × 3.5 × m ÷ 200 × t
- v
- Walking speed (km/h)
- m
- Body weight (kg)
- t
- Time walking (min)
- MET
- Intensity, clipped to 2–8
- E
- Calories burned (kcal)
MET estimate = 1.5+0.5v clipped to 2–8; kcal = MET×3.5×kg÷200×minutes. This is a simplified estimate, not a personal measurement.
Frequently asked questions
How does the estimate work?
It estimates MET as 1.5 + 0.5 × speed in km/h, clipped to 2–8, then applies MET × 3.5 × body weight in kg ÷ 200 × minutes. MET and energy expenditure vary between people and conditions, so this is only a rough estimate.
