Calories Burned Calculator
Use this calculator to estimate the calories you burn from various physical activities based on your weight and exercise duration. The results are based on MET (Metabolic Equivalent of Task) values which estimate energy expenditure during physical activities.

About the Calories Burned Calculator
This calculator estimates the number of calories you burn during various physical activities based on your weight and the duration of the activity. The calculation uses MET (Metabolic Equivalent of Task) values which represent the energy cost of physical activities.
How Calories Burned Are Calculated
The formula used to calculate calories burned is:
Calories Burned = MET × Weight (kg) × Time (hours)
Where:
- MET (Metabolic Equivalent of Task) is a unit that estimates the energy used by the body during physical activity, compared to resting metabolism.
- Weight is your body weight in kilograms (converted from pounds if needed).
- Time is the duration of the activity in hours.
Understanding MET Values
MET values are standardized measures that allow comparison of energy expenditure across different activities:
- 1 MET = Resting metabolic rate (calories burned at complete rest)
- 2-3 METs = Light activity (e.g., slow walking)
- 3-6 METs = Moderate activity (e.g., brisk walking, cycling)
- 6+ METs = Vigorous activity (e.g., running, swimming laps)
Factors Affecting Calorie Burn
While this calculator provides a good estimate, actual calories burned may vary based on:
- Individual metabolism
- Body composition (muscle burns more calories than fat)
- Exercise intensity and efficiency
- Environmental conditions (temperature, altitude)
- Fitness level
