How does this calculator estimate calories burned?

This calculator uses MET (Metabolic Equivalent of Task) values — a standardized measure of how much energy an activity requires relative to resting quietly — to estimate calories burned for a given activity, weight, and duration.

Because more massive bodies expend more energy performing the same movement, your body weight is a core input alongside the activity type and how long you did it.

How is calorie burn calculated?

Multiply the activity’s MET value by your weight in kilograms and the duration of the activity in hours to get an estimated calorie burn.

Formula

Calories burned = MET × weight (kg) × duration (hours)

Example: Running (MET 9.8) × 70 kg × 0.5 hr ≈ 343 calories
