Frequently asked questions
What is a MET value?
Metabolic Equivalent of Task — a standardized measure of how much energy an activity uses relative to resting. A MET of 8 means the activity uses roughly 8 times the energy of sitting still. This calculator uses widely-cited reference values for each activity.
How accurate is this?
It's a reasonable estimate based on population-average MET values — actual calorie burn varies with intensity, fitness level, and individual metabolism, so treat the result as a ballpark figure rather than a precise measurement.
