Frequently asked questions
What is the formula for the calories burned by activity calculation?
Calories burned (kcal) = met × w × t / 60. Here met is activity (MET), w is weight (kg), t is duration (min).
What inputs do I need for the calories burned by activity (met) calculator?
You need activity in MET, weight in kg, duration in min. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use this calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
