AI Website GeneratorEstimate how many calories you burn during exercise, workouts, and everyday physical activities.
Enter your body weight, workout duration, and activity to estimate your calorie burn.
This calculator uses average MET values to estimate energy expenditure. Actual calorie burn varies with fitness level, movement efficiency, exercise intensity, and individual characteristics. Total calories include the energy your body would have used at rest during the same period.
The number of calories you burn during physical activity depends on factors such as your body weight, exercise duration, and intensity. One common way to estimate energy expenditure is to use MET values, which represent the metabolic demands of different activities.
MET stands for Metabolic Equivalent of Task. One MET represents an approximate resting metabolic rate. Activities with higher MET values generally require more energy when performed for the same amount of time.
Calories (kcal) ≈ MET × Body Weight (kg) × Duration (hours)
This simplified formula assumes that one MET corresponds to approximately one kilocalorie per kilogram of body weight per hour. When you enter your weight in pounds, the calculator converts it to kilograms automatically.
| Activity | MET Value |
|---|---|
| Moderate Walking | 3.5 |
| General Strength Training | 3.5 |
| Moderate Cycling | 6.8 |
| Jogging – About 5.0 mph (8 km/h) | 8.3 |
| Running – About 6.2 mph (10 km/h) | 9.8 |
| Vigorous Circuit Training | 8.0 |
Total calories burned include both the energy required for physical activity and the energy your body would have used at rest during that time. Active calories represent the estimated additional energy expenditure above the resting level.
The calculator estimates active calories by subtracting one MET from the activity's MET value. This provides a simplified estimate rather than a direct measurement.
Calorie expenditure during strength training can vary significantly based on exercise selection, lifting intensity, rest periods, training volume, and movement speed. A general MET estimate cannot fully capture these differences.
This calculator is designed for general guidance and comparisons between activities. It does not measure your actual metabolic rate or account for every individual factor. Treat the results as estimates rather than exact values.
Enter your body weight in pounds or switch to kilograms. Your weight is automatically converted when changing units. Running speeds are shown in miles per hour for U.S. units and kilometers per hour for metric units. Calorie results are always displayed in kilocalories (kcal).
