Understanding BMI Prime

What is BMI Prime?

BMI Prime is a modification of the traditional Body Mass Index (BMI) that makes it easier to understand across different populations and ethnicities. It's calculated by dividing your BMI by 25, which represents the upper limit of the healthy weight range.

Formula:

BMI Prime = BMI / 25

BMI = Weight (kg) / Height² (m²)

Why Use BMI Prime?

BMI Prime provides several advantages over traditional BMI:

  • Universal interpretation: BMI Prime < 1.0 indicates healthy weight for all ethnicities
  • Easier to understand: Values directly relate to healthy weight ranges
  • Better for international comparisons across different populations
  • More accurate for diverse body types and ethnic backgrounds
