Calories Burned Calculator
Choose an activity, enter your body weight and workout duration, and see an estimate based on published MET values. Compare gross calories with active calories above resting energy.
How does this calories burned calculator work?
It estimates gross calories as MET × weight in kilograms × minutes ÷ 60, using the conventional approximation of 1 kcal/kg/hour for 1 MET. The activity values are examples from the 2024 Adult Compendium of Physical Activities. A MET estimate is not a measurement of your personal calorie use.
Frequently asked questions
How does this calories burned calculator work?
It estimates gross calories as MET × weight in kilograms × minutes ÷ 60, using the conventional approximation of 1 kcal/kg/hour for 1 MET. The activity values are examples from the 2024 Adult Compendium of Physical Activities. A MET estimate is not a measurement of your personal calorie use.
Are my weight and activity uploaded?
No. The estimate runs in your browser. Your inputs are not uploaded or saved by this tool.
What is the difference between gross and active calories?
Gross calories include the conventional resting-energy amount for the workout time. Active calories subtract that 1-MET reference. Neither is an individualized measurement.
Why can this estimate differ from my watch?
MET values describe population-level activity intensity. Personal effort, fitness, body composition, terrain and measurement method can change actual energy use.
Can I use this to plan weight loss or decide how much to eat?
No. The estimate is not a diet, weight-loss or medical recommendation. Do not use it to set food intake or replace advice from a qualified health professional.
