Calories Burned Calculator

This Calories Burned Calculator estimates how much energy an activity uses with the well-established MET method.

MET stands for "metabolic equivalent of task": one MET is roughly your resting metabolic rate, and a brisk run might be ten METs, meaning it burns about ten times the energy of sitting still.

The tool multiplies the activity’s MET by your body weight and how long you exercised to give a calorie figure that scales sensibly with effort and size.

Choose from common activities — walking, jogging, running, cycling, swimming, hiking, rowing, yoga, weightlifting, jumping rope, dancing or the elliptical — each pre-loaded with a representative MET for moderate effort.

If your activity is not listed, switch to custom MET and type any value from a published compendium of physical activities.

Enter your weight in kilograms and the duration in minutes, and you immediately see the total kilocalories burned plus a per-minute and per-hour breakdown so you can compare intensities at a glance.

The estimate is a population average, not a lab measurement: actual burn varies with fitness, terrain, pace and individual metabolism, so treat the number as a useful ballpark for planning workouts or food intake.

Everything is computed locally in your browser, with no data uploaded or stored, and it keeps working offline once the page has loaded.
