SOURCE·2024 Adult Compendium of Physical Activities·REVIEWED JUL 2026

How this is worked out

  1. Take the activity's MET value from the 2024 Adult Compendium of Physical Activities — the measured ratio of its energy cost to sitting quietly.
  2. Convert MET to a rate using the ACSM relationship: multiply by 3.5, then by body mass in kilograms, then divide by 200. That gives kilocalories per minute.
  3. Multiply the rate by the number of minutes actually spent.
  4. Round to whole kilocalories. Nothing else is applied — no age factor, no sex factor, no proprietary adjustment, because the underlying data does not support one.
kcal/min = MET × 3.5 × mass(kg) ÷ 200
kcal     = kcal/min × minutes
