How to use Calories Burned Calculator

1. Prepare the required inputs

Estimate gross exercise calories from body weight, duration and your chosen MET value. Use the units and options beside each field. Results update as inputs change; reset returns to example inputs.

Weight (kg): minimum 1, maximum 500
Duration (minutes): minimum 1, maximum 1440
Activity intensity (MET): minimum 1, maximum 25

2. Try a worked example

70 kg, 30 minutes and 3.5 MET gives approximately 128.6 gross kcal.

3. Understand the calculation

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

4. Read the assumptions

Includes resting energy during the activity. Choose a MET value appropriate to the actual activity and pace. Fitness, terrain and measurement error affect actual calories.

5. Check and compare results

Match entered values to their labels and units. Review output labels alongside the assumptions, then change one input at a time. A currency selector changes display labels without converting amounts. Use the available save or copy actions and retain the input values so the estimate can be reproduced.

6. Fix an invalid input

Complete required fields and respect the listed bounds. Check date order, age relationships and mode-specific requirements where relevant; the error message identifies invalid combinations. Reset to example inputs to recover. A valid calculation applies to its stated model and does not verify a real-world outcome.
