How the Calories Burned Calculator works

Each activity has a MET value (metabolic equivalent) from the Compendium of Physical Activities. One MET is roughly 1 calorie per kilogram per hour at rest.

Calories ≈ MET × Weight(kg) × Hours

Step-by-step calculation

  1. 1Choose the activity.
  2. 2Enter weight and minutes.
  3. 3Calories = MET × kg × hours.

Worked example

A 70 kg person walking briskly (3.5 mph, 4.3 METs) for 30 minutes burns about 4.3 × 70 × 0.5 ≈ 151 calories.
