This is an estimate, not a medical measurement. Real calorie burn varies from person to person.
STEP 02
Make it personal
Your body weight and time make the estimate much more useful than a one-size-fits-all number.
STEP 03
See it your way
Compare the result with everyday activities so the number feels easier to understand.
Built on a trusted method
Useful, honest estimates.
We use MET values—the standard way to compare the energy cost of physical activities—and show a range because bodies and conditions differ.
No false precision
The middle number is a practical estimate. The range is there to keep it honest.
No judgement
Movement is more than a calorie number. This tool informs; it does not grade your day.
How is the estimate calculated?+
The calculator combines the activity’s MET value with your weight and duration. The formula estimates total energy used during the activity. Fitness, technique, terrain, temperature, and individual metabolism can all change the real result.
