Frequently Asked Questions

What is MET?

MET (Metabolic Equivalent of Task) is the ratio of exercise oxygen consumption to resting oxygen consumption. A higher MET indicates a more intense activity. The formula used is: Calories = MET × weight (kg) × time (hours).

Will the result differ from my actual calorie burn?

Yes. Actual calories burned vary by individual factors such as muscle mass, fitness level, and exercise intensity. This calculator uses MET-based averages and is intended as a reference estimate.
