Treadmill Calorie Calculator

The MET value shown beside each activity is the 2024 Adult Compendium value for that activity code.
A five-digit 2024 Adult Compendium code, e.g. 17200 for brisk walking. Overrides the activity chosen above and reaches all 1111 activities.
Only used when the activity is set to "Enter my own MET value".
Metric uses kilograms and centimetres; US uses pounds with feet and inches; UK uses stones and pounds.
Body weight: kilograms (metric), pounds (US) or whole stones (UK).
Only used with UK stones-and-pounds: the pounds part, e.g. 11 st 4 lb is weight 11 and extra pounds 4.
Gross is what fitness trackers report. Net is the honest "extra" figure when you are eating exercise calories back.
Used when the unit system is metric.
Used when the unit system is US or UK.
The inches part of a feet-and-inches height.
Only used by the corrected-MET adjustment.

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
  1. Walking, treadmill, 3.5 to 3.9 mph (5.6 to 6.3 km/h), 0% grade (Compendium code 17358) = 4.8 MET
  2. Duration = 30 min = 0.5 h; body weight = 70 kg
  3. Gross energy = 4.8 MET x 70 kg x 0.5 h = 168 kcal
  4. Net energy = (4.8 - 1) x 70 x 0.5 = 133 kcal
