Whether you're tracking your fitness progress, planning weight loss goals, or just curious about your energy expenditure, this tool provides instant, accurate calculations based on scientifically validated methods.

How It Works

The calculator uses MET (Metabolic Equivalent of Task) values to determine calorie expenditure. MET represents the energy cost of physical activities as multiples of resting metabolic rate. The formula used is:

Calories = MET × Weight (kg) × Duration (hours)

Frequently Asked Questions

How accurate is the calorie calculation?

Our calculator uses standardized MET values from the Compendium of Physical Activities, making it highly accurate for most individuals. However, actual calorie burn can vary based on factors like age, gender, body composition, and exercise intensity.

What is MET and how is it used?

MET (Metabolic Equivalent of Task) is a unit that estimates the energy cost of physical activities. One MET is defined as the energy expenditure while sitting at rest. Our calculator multiplies the MET value of an activity by your weight and the duration to estimate calories burned.

Why does weight affect calorie burn?

Heavier individuals burn more calories performing the same activity because moving more mass requires more energy. This is why weight is a critical factor in our calculations.

Can I use this tool for weight loss planning?

Absolutely! Understanding your calorie expenditure is essential for creating an effective weight loss plan. Combine this calculator with tracking your calorie intake to ensure you maintain a calorie deficit for weight loss.

Do I need an account to use this tool?

No, our calorie burn calculator is completely free to use without registration. All calculations happen in your browser, and no personal data is collected or stored.
