  3. Verify assumptions before applying the result.

Formula

gross kcal = MET × 3.5 × weight kg / 200 × minutes; net above-rest kcal = (MET − 1) × 3.5 × kg / 200 × minutes (Compendium of Physical Activities)

MET values are Compendium general-activity values (Ainsworth et al.); individual speed, grade, technique and physiology change actual energy use. The §C preset activity pages reuse this same MET table.

Frequently asked questions

About 220 kcal gross at 154 lb (70 kg) using the Compendium value of 6 METs — 183 kcal above what you would burn resting.

About 440 kcal per hour at 154 lb, or roughly 73 kcal every 10 minutes. Scale in proportion to your own body weight.

6 METs, the Compendium of Physical Activities (Ainsworth et al.) value for "Swimming, leisurely general". One MET is resting energy use, so this activity costs about 6 times the resting rate.

About 68 minutes at 154 lb at the full 6 MET intensity. Rest breaks and lower-effort stretches extend the real time needed.

The formula scales with body weight: at 120 lb the same 30 minutes costs about 171 kcal and at 200 lb about 286 kcal. Technique, terrain and fitness shift the individual result further, typically by ±15–20%.
