About the Calories Burned Calculator
The calories burned calculator estimates the energy you use during an activity from its MET value, your body weight and the duration. A MET (metabolic equivalent of task) compares an activity with resting: 1 MET is the energy used sitting quietly, so an activity rated 9.8 METs burns about 9.8 times as much. The calculator uses the standard formula kcal = MET × 3.5 × weight (kg) ÷ 200 × minutes, with MET values from the Compendium of Physical Activities. Results are averages; your actual burn depends on intensity, fitness and terrain.
How to use it
- 1Enter your body weight in kilograms.
- 2Enter how many minutes the activity lasted.
- 3Choose the activity from the list.
- 4Press Calculate to see the estimated calories burned.
Worked example
a 70 kg person running at 10 km/h (9.8 METs) for 30 minutes burns about 9.8 × 3.5 × 70 ÷ 200 × 30 ≈ 360 kcal. Walking at 5 km/h (3.5 METs) for the same time burns about 129 kcal.
How it works
Formula
kcal = MET × 3.5 × weight(kg) / 200 × minutes. MET is the metabolic equivalent of the activity.
Who it is for
People tracking exercise for weight management and anyone comparing the energy cost of different activities.
Why it helps
It puts a rough number on exercise so you can compare activities and plan food intake around training.
Common use cases
- Comparing running, cycling and swimming for the same time
- Estimating how long to walk to burn a given number of calories
- Logging exercise in a food-tracking app
Frequently asked questions
A:A MET is the ratio of an activity’s energy cost to resting metabolism; 1 MET is sitting quietly.
