Calories Burned Calculator — FAQ

Pick an activity from the list, enter your body weight and how long you did the activity, and the tool multiplies the activity's MET value by your weight in kilograms and the duration in hours to estimate the calories burned. The result updates instantly — no button to click.

MET stands for Metabolic Equivalent of Task — a standard measure of how intense an activity is compared to sitting at rest (which is defined as 1 MET). A MET of 8 means the activity uses about 8 times as much energy per minute as resting. Higher MET = more energy used per minute at the same body weight.

Yes. Use the Metric / Imperial toggle to switch between kilograms and pounds. The calculator converts to kilograms internally for the MET formula, so the result is always consistent regardless of which unit you use.

The MET formula accounts for body mass because moving a heavier body generally requires more energy. For the same activity, intensity, and duration, a heavier person burns more calories. That's why weight is a required input rather than just optional.

It's a general estimate based on average MET values from published research (the Compendium of Physical Activities). Actual calorie burn varies with your individual fitness level, effort intensity, body composition, terrain, temperature, and metabolism — so treat the figure as a useful guide rather than an exact measurement.

MET values are defined relative to rest, so the formula estimates the energy used by the activity itself — not your total daily calorie expenditure. If you need your full daily burn including rest, see the TDEE Calculator.

No. Everything is calculated directly in your browser. Your weight, duration, and activity choice are never sent to a server or stored anywhere.
