MET values, by activity

Every option in the dropdown above carries a MET, short for Metabolic Equivalent of Task, drawn from the Compendium of Physical Activities, the standard reference exercise scientists use to compare the energy cost of different activities. A MET of 1 is roughly your resting energy use; a MET of 8 means the activity burns about eight times that.

Compendium of Physical Activities MET values, run through the formula below for a 160 lb person; the calculator above scales this to your own weight and duration.

The math behind the number

The formula is cal/min = MET × 3.5 × body weight in kg ÷ 200. A 160 lb runner (about 72.6 kg) at 6 mph, MET 9.8, works out to roughly 12.4 calories a minute; over a 30-minute run that's about 373 calories, the same number this calculator returns for those inputs.

Duration and weight move the total the most. Doubling either one roughly doubles the calorie estimate; picking a slightly wrong activity from the list moves it far less.

FAQs

Where do these MET values come from?

From the Compendium of Physical Activities, a reference list of energy costs for hundreds of activities used throughout exercise science. The dropdown above uses a representative MET for each activity category, not a lab measurement of you specifically.

Why does the same activity have different calorie totals for two people?

Because the formula scales with body weight. A 200 lb person and a 130 lb person doing the same activity at the same intensity burn different totals because moving more mass costs more energy.

Does a higher MET always mean harder effort?

Generally yes. MET is a multiple of resting energy use, so a MET of 8 means an activity uses roughly eight times the energy you'd burn sitting still. It's a rough intensity ranking, not a precise effort score.

Is this the same number my fitness tracker shows?

Close, but not identical. Trackers blend MET tables with your heart rate and movement data, which usually narrows the estimate. A MET calculation like this one is a reasonable starting point without a device.
