How it is calculated
kcal per minute = MET × 3.5 × weight (kg) ÷ 200
A MET (metabolic equivalent) compares an activity with sitting at rest. The values come from the 2024 Adult Compendium of Physical Activities. Example: a 170 lb person running at 5 mph (8.5 MET) for 30 minutes burns about 344 kcal.
Why your number may differ
- MET values are averages; fitness, technique, terrain and intensity change the real figure.
- The result is gross calories – it includes the calories you would have burned at rest anyway.
- Fitness trackers estimate differently and often show other numbers.
Frequently asked questions
How many calories does walking burn?
At 3 mph (3.5 MET), a 170 lb person burns about 142 kcal in 30 minutes.
Does a heavier person burn more calories?
Yes – the same activity costs more energy for a heavier body, so the estimate grows in proportion to weight.
