Remember that BMI is just one indicator of health and doesn't account for factors like muscle mass or body composition.

BMI Formula

Metric Units

BMI = weight (kg) / height² (m)

Example: For a person who is 1.75m tall and weighs 70kg

BMI = 70 / (1.75 × 1.75) = 22.9

Imperial Units

BMI = 703 × weight (lbs) / height² (in)

Example: For a person who is 5'9" (69 inches) and weighs 150lbs

BMI = 703 × 150 / (69 × 69) = 22.1

  • Malnutrition

Understanding BMI Limitations

While BMI is a useful screening tool, it has limitations. It doesn't directly measure body fat and doesn't account for:

  • Muscle mass
  • Bone density
  • Overall body composition
  • Distribution of fat
  • Age and sex differences
  • Ethnic differences

For example, athletes may have a high BMI due to increased muscle mass rather than increased body fat. Similarly, older adults may have a normal BMI but still have excess body fat.
