Calories Burned Calculator

What is the Calories Burned Calculator?

Estimate calories burned during exercise using MET values from the Compendium of Physical Activities. Calories burned depend on your body weight and the intensity of the activity, measured in MET values from published research.

How to use the Calories Burned Calculator

1. Enter your body weight, your activity, your duration.
2. Results update automatically as you type; you can also press Calculate.
3. Read the output: calories burned, per hour.
4. Use the 📊 chart to see the result visually, then copy or share it.

Formula and method

Worked example

With body weight = 70 kg, activity = Running 5 mph, duration = 30 minutes, the Calories Burned Calculator returns calories burned: 294 kcal; per hour: 588 kcal/h.

Where the Calories Burned Calculator helps in real life

You walked briskly for 45 minutes and want to log it. Select the activity and your weight to estimate calories burned.

You are choosing between cycling and swimming for fitness. Comparing the same duration shows which activity uses more energy for your body.

Common mistakes to avoid

• Assuming fitness trackers are always accurate.
• Using an activity intensity higher than what you actually did.
• Eating back every calorie burned without considering estimation errors.
• Forgetting that the same activity burns more for heavier people.

💡 Practical tip: MET values are averages from research — your actual burn may be higher or lower.

Tips for better results

• Choose the closest intensity level honestly.
• Use the result as an estimate, not an exact figure.
• Combine with the calorie calculator for daily targets.
