For general wellness only. These results are estimates from published formulas and guidelines, not a diagnosis or medical advice. They may not suit pregnancy, children, older adults, athletes or people with health conditions. Talk to a qualified health professional about your health. In an emergency, call your local emergency number.

How to use the calories burned calculator

Energy used = MET × body weight in kg × hours. One MET is about 1 kcal per kg per hour. MET values come from the 2024 Adult Compendium of Physical Activities, used unchanged with their activity codes as the Compendium asks. Speeds are shown in mph as published, with km/h added.

  1. Enter your weight.
  2. Pick the activity closest to what you did.
  3. Enter the duration in minutes.
  4. Read the estimate in kcal and kJ.

Understanding your result

The result is the total energy used during the activity, including what your body would burn at rest anyway. Heavier people use more energy for the same activity. Treat it as an average: fitness, technique and terrain can change the real figure.

Questions

Why is my fitness tracker different?
Trackers estimate from heart rate and movement, while this uses average values from published studies. Both are estimates.
I’m over 60. Is this accurate for me?
The values are for adults aged 19 to 59. A separate Older Adult Compendium gives adjusted values for people aged 60 and over, which tend to differ because resting energy use is lower.
Can I combine two activities?
Work them out one at a time and add the results. The Compendium asks users not to average MET values of different activities.
Is this a diagnosis?
No. It compares your numbers with published ranges for general wellness. Only a qualified health professional can assess your health, taking your history and other tests into account.
