What This Calculator Does
The Calories Burned Calculator estimates energy expenditure during exercise using metabolic equivalents, known as METs. Runners, cyclists, and gym-goers use it to quantify each session and balance their training against nutrition.
How It Works
One MET equals the energy burned sitting still. Activity is scored in METs, and calories equal MET x 3.5 x weight (kg) / 200 x minutes. Since body weight is in the formula, heavier individuals burn more for identical effort.
Example
A 70 kg person cycling at a MET of 7 for 45 minutes burns 7 x 3.5 x 70 / 200 x 45 = about 386 kcal.
Formula
kcal = MET × 3.5 × Weight (kg) / 200 × Minutes3.5 ml O₂/kg/min = 1 MET baseline.
Reading the Results
Calories Burned
Total energy expenditure for the session, computed from the activity MET value, your weight, and duration.
Frequently Asked Questions
What is a MET?
A metabolic equivalent rates how many times resting metabolism an activity demands. Running scores around 9.8, brisk walking around 3.5.
How accurate is this estimate?
It is a solid estimate based on published MET values, accurate to roughly 10-15% for most activities and intensities.
Should I eat back exercise calories?
Not necessarily. Activity trackers overestimate, and many people undo workouts by over-rewarding themselves at meals.
