What Is a MET Value?

MET stands for Metabolic Equivalent of Task. A MET of 1.0 equals the energy your body burns at rest (roughly 1 kcal per kg per hour). An activity with a MET of 8 burns 8 times the energy of sitting still. MET values are published by the Compendium of Physical Activities and are the standard method used by fitness trackers and clinical research to estimate calorie expenditure.

The MET Calorie Formula

The formula to convert MET to calories per unit of time is:

kcal/min = MET × weight (kg) × 3.5 ÷ 200

For a 30-minute session: kcal = MET × weight (kg) × 3.5 ÷ 200 × 30

For a 70 kg person this simplifies to approximately kcal/30 min ≈ MET × 18.4.

Calories Burned per 30 Minutes (70 kg / 154 lb) — kcal

Values below are calculated using the MET formula for a 70 kg person performing 30 minutes of each activity at the stated intensity.

Same Activities in Kilojoules (kJ)

To convert kcal to kJ, multiply by 4.184. The table below shows the kJ equivalent for each activity (70 kg, 30 minutes).

Adjusting for Your Body Weight

The MET formula scales linearly with weight. If you weigh 90 kg instead of 70 kg, multiply the kcal values above by 90/70 ≈ 1.29. A 50 kg person would multiply by 50/70 ≈ 0.71. Heavier individuals burn more calories performing the same activity at the same intensity because more mass must be moved.

Limitations of MET-Based Estimates

  • MET values assume average fitness and do not account for individual metabolic variation (±15–20%).
  • Terrain, heat, and elevation can raise effective MET by 10–30%.
  • Calorie burns from strength training are harder to estimate — MET values undercount post-exercise oxygen consumption (EPOC).
  • For clinical or performance nutrition, use measured indirect calorimetry rather than MET estimates.
