Example walkthrough
Try the calculator example: Brisk walk: 3.8 MET, 70 kg, 45 min. The example result is About 210 kcal.
- For a brisk walk at 3.8 MET, the calculator multiplies MET by weight and duration.
- A heavier body weight or longer duration increases the estimate.
Formula and steps
Calories per minute are estimated as MET x 3.5 x weight in kg / 200, then multiplied by duration.
The formula line on the calculator page is there so the answer is not a mystery. Read it when you need to understand where the number came from.
