Enter the distance in miles and the intensity in METs (Metabolic Equivalent of Task) into the calculator to determine the Mi Factor. The Mi Factor is a measure of physical activity that combines both distance and intensity.

Mi Factor Formula

The following formula is used to calculate the Mi Factor.

Mi = D * I

Variables:

  • Mi is the Mi Factor
  • D is the distance traveled (miles)
  • I is the intensity of the activity (METs)

To calculate the Mi Factor, multiply the distance traveled in miles by the intensity of the activity measured in METs.

What is a Mi Factor?

The Mi Factor is a metric used to quantify the amount of physical activity or exercise, taking into account both the distance of the activity and its intensity level. It is useful for comparing different types of activities and for tracking progress in fitness programs. The Mi Factor can help individuals understand how much energy they are expending during various activities.

How to Calculate Mi Factor?

The following steps outline how to calculate the Mi Factor.


  1. First, determine the distance traveled (D) in miles.
  2. Next, determine the intensity of the activity (I) in METs.
  3. Next, gather the formula from above = Mi = D * I.
  4. Finally, calculate the Mi Factor (Mi).
  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.

Distance traveled (D) = 5 miles

Intensity of the activity (I) = 8 METs
