How do you calculate BMI in the metric system?

With the metric system, the formula for BMI is weight in kilograms divided by height in meters squared.

Are BMI and FM the same?

Objective: A general assumption is that the body mass index (BMI) reflects changes in fat mass (FM). However, it fails to distinguish the type of weight that is lost or gained-fat mass (FM) or fat-free mass (FFM). The BMI treats both changes the same although they have opposite health consequences.

How do you calculate square meters with BMI?

BMI is calculated by taking the body weight in kilograms (kg) and dividing it by the height in meters (m) squared.

  1. 5 feet, 4 inches = 64 inches.
  2. 64 inches x 2.54 cm/inch = 162.56 cm.
  3. 162.56 cm = 1.625 meters.
  4. Square the height (1.625 x 1.625) = 2.64 m.
