How to Calculate: The Calorie Burn Rate Calculator Formula
Uses clinical Metabolic Equivalent of Task (MET) coefficients from the Compendium of Physical Activities where 1 MET = resting baseline energy.
Step-by-Step Calculation Guide
- Select activity or sport from the MET database.
- Input duration in minutes.
- Enter current body weight in kilograms or pounds.
- Review total calories burned and hourly burn rate.

Frequently Asked Questions about Calorie Burn Rate Calculator
What is a MET value?
One Metabolic Equivalent of Task (1 MET) is defined as the amount of oxygen consumed while sitting at rest (3.5 ml of O2 per kg per minute). An activity with a MET of 6 burns 6 times resting energy.
Why does body weight impact calories burned so heavily?
Moving a heavier mass against gravity requires proportionally more muscular work and kinetic energy, directly increasing oxygen uptake and calorie burn.
What is the 'Afterburn Effect' (EPOC)?
Excess Post-Exercise Oxygen Consumption (EPOC) is the additional calories your body burns after high-intensity exercise to restore glycogen, repair muscle fibers, and clear lactic acid.
Do fitness watches accurately display calories burned?
Most commercial heart-rate wearables have a 15% to 30% margin of error on caloric expenditure, generally overestimating calories burned during cardio.
