What is the Calories Burned Calculator?
Pick an activity, enter your body weight and how long you did it, and get the calories burned, per hour and per minute figures. The formula is calories = MET × weight (kg) × hours, where the MET value comes from the Compendium of Physical Activities.
You also see the ten activities that burn the most calories for your weight and time, plus what the result equals in food. Results are estimates (about ±15 percent) because fitness, terrain and effort all change the real burn.
