Calories Burned Calculator
Estimate the calories you burn in a workout from your body weight, activity, and time, using standard MET values.
How to Read Your Result
This calculator uses MET (metabolic equivalent) values: calories burned = MET x 3.5 x body weight (kg) / 200 x minutes. MET tables are averages, so real burn varies with intensity, fitness, and individual metabolism.
Higher body weight and higher intensity both increase calories burned.
Wearable trackers and machines are estimates too - treat numbers as ballpark.
Pair activity with nutrition; you cannot reliably out-train a poor diet.
Frequently Asked Questions
How are calories burned calculated?
Using MET values: calories = MET x 3.5 x weight (kg) / 200 x minutes. Each activity has an average MET.
Why do estimates differ from my watch?
Devices use heart rate and other sensors with their own models. All methods are approximations.
Does weight affect calories burned?
Yes. Moving a heavier body costs more energy, so the same activity burns more calories at higher body weight.
