How the result is calculated
The selected metabolic-equivalent estimate is multiplied by body weight in kilograms and duration in hours. Published activity values are population averages; fitness, technique, terrain, temperature and individual metabolism can materially change actual energy use.
Method source: CDC activity-energy examples.
All calculation and transformation work happens in this browser tab. No entered value is sent to an Noler Tools application server.
