Worked out from Herrmann SD, Willis EA, Ainsworth BE, et al. - 2024 Adult Compendium of Physical Activities: A third update of the energy costs of human activities and 2 other sources.
The Compendium value is a laboratory average for adults aged 19-59; it does not know your fitness, technique or terrain.
This is the gross figure, which includes the resting metabolism you would have spent anyway. Use the net figure when adding exercise calories back to a daily target.
MET values are population averages measured in laboratory conditions on adults aged 19-59. Individual energy cost varies with fitness, technique, terrain, temperature and body composition, and machine and wearable estimates differ again. Treat the figure as an approximation.

How this is worked out
4 steps
Walking, treadmill, 3.5 to 3.9 mph (5.6 to 6.3 km/h), 0% grade (Compendium code 17358) = 4.8 MET
Duration = 30 min = 0.5 h; body weight = 70 kg
Gross energy = 4.8 MET x 70 kg x 0.5 h = 168 kcal
Net energy = (4.8 - 1) x 70 x 0.5 = 133 kcal
Figures from Compendium of Physical Activities (MET values), 2024 edition, checked 31 August 2026. Its 5 worked examples are re-run on every release, last on 15 September 2026. What changed · how reference data is kept current
Calories burned by an activity from its Compendium of Physical Activities MET value, body weight and duration, reported both gross and net of resting metabolism.
How to use this Treadmill Calorie Calculator
Enter Activity, Compendium activity code (optional), Custom MET value and Duration. Calories burned updates as you type. Change one figure at a time to see what drives the result.
How the result is worked out
Open “How this is worked out” beside the result for the step-by-step calculation behind Calories burned, Gross calories and Net calories above resting.
The method follows Herrmann SD, Willis EA, Ainsworth BE, et al. - 2024 Adult Compendium of Physical Activities: A third update of the energy costs of human activities, Ainsworth BE, Haskell WL, Herrmann SD, et al. - 2011 Compendium of Physical Activities: a second update of codes and MET values and Compendium of Physical Activities - Corrected METs (the 3.5 mL O2/kg/min standard MET and the Harris-Benedict correction procedure).

Understanding Calories burned, Gross calories and Net calories above resting
MET values are population averages measured in laboratory conditions on adults aged 19-59. Individual energy cost varies with fitness, technique, terrain, temperature and body composition, and machine and wearable estimates differ again. Treat the figure as an approximation.
