What Is a Calories Burned Calculator?
This calculator estimates how many calories you burn during a specific activity using MET (Metabolic Equivalent of Task) values — a standardized measure of how intense an activity is relative to resting.
Formula Used
Calories Burned = MET × Weight (kg) × Duration (hours)
Each activity has a MET value representing its energy cost relative to sitting quietly (1 MET). Higher MET values mean more calories burned per minute.
How to Use This Calculator
Select your weight unit, enter your weight, choose your activity from the dropdown, and enter the duration in minutes. Click "Calculate" for an instant calorie burn estimate.
Frequently Asked Questions
How accurate are MET-based calorie estimates?
MET values are population averages and provide a reasonable estimate, but actual calorie burn varies based on individual fitness level, intensity, and body composition.
Does body weight affect calories burned?
Yes, heavier individuals burn more calories doing the same activity because more energy is required to move greater body mass.
Why do different running speeds have different values?
Faster running requires more energy per minute, resulting in a higher MET value and more calories burned in the same time period.
Can I use this to plan weight loss?
Yes, combine this with our Calorie Calculator to understand your total daily calorie balance, including both intake and activity burn.
