Enter the power in Watts and the body weight in kilograms into the calculator to determine the Metabolic Equivalent. This calculator can also evaluate any of the variables given the others are known.

Watts To Mets Formula

The following formula is used to calculate the conversion from Watts to Mets.

M = W / (Wb * 3.5)

Variables:

  • M is the Metabolic Equivalent (Mets)
  • W is the power in Watts (W)
  • Wb is the body weight in kilograms (kg)

To calculate the Mets, divide the power in Watts by the product of the body weight in kilograms and 3.5. The number 3.5 is used because it is the estimated resting metabolic rate (RMR) for a typical adult at rest, measured in milliliters of oxygen consumed per kilogram of body weight per minute. This conversion allows for a more accurate understanding of how much energy is being used during a physical activity.

What is Watts To Mets?

Watts to Mets is a conversion used to measure the intensity of physical activities. A Met, or metabolic equivalent, is a unit that describes the energy expenditure of a specific activity. It is defined as the ratio of the rate of energy expended during an activity to the rate of energy expended at rest. On the other hand, a watt is a unit of power that measures the rate of energy conversion or transfer. Therefore, converting watts to Mets allows for a more accurate understanding of how much energy is being used during a physical activity.

How to Calculate Watts To Mets?

The following steps outline how to calculate the Metabolic Equivalent (Mets) using the formula: M = W / (Wb * 3.5).


  1. First, determine the power in Watts (W).
  2. Next, determine the body weight in kilograms (Wb).
  3. Next, gather the formula from above = M = W / (Wb * 3.5).
  4. Finally, calculate the Metabolic Equivalent (Mets).
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

power in Watts (W) = 120

body weight in kilograms (Wb) = 70
