How Calories Burned Calculator works
Methodology for the Calories Burned Calculator: formulas, coefficients, data sources, assumptions, and known limitations.
Scope
Generic MET-based calorie estimator for any activity in the Compendium of Physical Activities.
Formula
kcal = MET * weight_kg * duration_h.
Coefficients
| Parameter | Value | Note |
|---|---|---|
| Range | 1.0 – 23.0 MET |
Data sources
- Ainsworth BE, Haskell WL, Herrmann SD, et al. 2011 Compendium of Physical Activities. Med Sci Sports Exerc. 2011;43(8):1575-1581. — PMID 21681120. Source of all MET values used in the tool.
- Compendium of Physical Activities — online tables (Arizona State University). — Public MET table hosted by the Compendium authors.
Assumptions
- Activity intensity matches the selected MET value.
Approximation range
Individual variance around the MET table is typically +/- 10–15%.
Limitations
- MET tables do not model fitness level, so the same workout returns the same kcal for a beginner and an elite athlete.
Reproducibility
Running 6 mph (10 MET), 70 kg, 30 min: kcal = 10 * 70 * 0.5 = 350 kcal.
