For education and planning only. This estimate is not medical advice, diagnosis, or a personalized exercise prescription.

What this calculator tells you

MET values express activity energy cost relative to a standard resting value. They make a transparent estimate possible without pretending a watch or machine can know exact expenditure.

How to use the Calories Burned Calculator

  1. 1

    Choose an activity or matching MET intensity.

  2. 2

    Enter body weight and active minutes.

  3. 3

    Treat the result as a range-level estimate.

Formula and interpretation

Method

Estimated kcal = MET × 3.5 × weight(kg) ÷ 200 × minutes.

How to read the result

Use the number to compare broad activities, not to eat back an exact calorie amount. Individual efficiency and resting metabolism vary.

Important limitations

Standard METs are group estimates. Age, fitness, technique, terrain, temperature, and actual intensity can change energy use substantially.

Calories Burned Calculator questions

Why does my watch show a different number?

Wearables add proprietary heart-rate and movement models, while this tool uses a transparent standard MET equation.

Are exercise-machine calorie displays accurate?

They are estimates and may not know your physiology or actual workload. Use one method consistently for trends.
