How Our Calories Burned Calculator Works
Our advanced 2026 calories burned calculator uses scientifically validated formulas to provide you with accurate calorie expenditure estimates for over 100 different activities. The calculation is based on the Metabolic Equivalent of Task (MET) system, which is the standard method used by health professionals worldwide.
The Science Behind MET Values
The Metabolic Equivalent of Task (MET) is a unit that estimates the amount of energy used by the body during physical activity, compared to resting metabolism. One MET is defined as the energy it takes to sit quietly, which for the average adult is about 1 calorie per kilogram of body weight per hour.
Our calculator uses the following formula:
For example, if you weigh 70 kg and go running (MET value of 8) for 1 hour:
8 MET × 70 kg × 1 hour = 560 calories burned
We source our MET values from the Compendium of Physical Activities, which is regularly updated with the latest exercise physiology research.

Frequently Asked Questions
Find answers to common questions about calories burned calculation and our tool.
Our calculator provides estimates based on established MET values and widely accepted formulas. While individual results may vary due to factors like metabolism efficiency, muscle mass, and exercise form, our tool offers scientifically grounded estimates accurate for most people. For precise medical assessments, consult a healthcare professional.
Several factors influence calorie expenditure:
- Body weight: Heavier individuals burn more calories performing the same activity
- Exercise intensity: Higher intensity equals more calories burned per minute
- Duration: Longer exercise sessions burn more total calories
- Fitness level: Fitter individuals may burn fewer calories for the same activity as they become more efficient
- Age and gender: Metabolic rates vary with age and between genders
- Body composition: Muscle tissue burns more calories than fat tissue, even at rest
Heart rate provides a more personalized estimate of exercise intensity. When you enter your heart rate, we use the Karvonen formula to adjust the MET value based on your exertion level. This is especially useful for activities where intensity varies, like interval training or sports.
Absolutely! Our calculator is excellent for weight loss planning. Combine it with our Calorie Calculator to determine your daily needs. A safe weight loss target is 0.5-1 kg (1-2 lbs) per week, which requires a daily deficit of 500-1000 calories. Our tool helps you see how different activities contribute to that deficit.
MET values vary based on exercise intensity and form. For example, "running" has different MET values for jogging (7 METs), running at 8 km/h (8 METs), and running at 12 km/h (12.5 METs). Our calculator accounts for these variations through our intensity selector and detailed activity database.
