How to Use

Enter your body weight, because calorie-burn estimates depend heavily on how much mass you are moving during the activity.
Set the duration of the workout or activity as accurately as possible. A ten-minute error can materially change the estimate for longer sessions.
Choose the activity that best matches what you actually did, including pace or intensity when that matters. Picking the closest real effort gives a more useful result than picking the most flattering one.
Review the calorie-burn estimate as a planning tool, not a precision measurement. Wearables, exercise machines, and calculators all produce ranges rather than exact numbers.
Use the result for broader training or nutrition decisions, such as adjusting intake, comparing workout types, or understanding how activity fits into your total daily energy burn.

Frequently Asked Questions

What does MET mean?

MET stands for metabolic equivalent of task. It is a standardized way to describe how demanding an activity is compared with resting, and many calorie-burn estimates are built from MET values plus body weight and time.

Are calories-burned estimates exact?

No. They are practical estimates based on body weight and typical intensity values. Real-world calorie burn can vary with fitness level, exercise efficiency, terrain, temperature, and how hard you actually worked.

Why does body weight matter so much?

Heavier bodies usually require more energy to move through the same activity, which tends to increase calorie burn. That is why the same workout can have meaningfully different estimates for different people.

Can I use this for cardio and strength workouts?

Yes. The calculator is useful for common cardio sessions, general exercise, and strength work, but resistance training estimates are usually a bit less precise because rest periods and lifting style vary so much.
