BMI is a quick reference, not a diagnosis. Use different guidance for children, pregnancy, illness, athletes, or major body-composition differences.

Formula

Weight in kg divided by height in meters squared.

Reference

A quick adult screening category.

How BMI works

BMI divides body weight by height squared. For the same height, more weight raises BMI. Taller height lowers BMI for the same weight.

Usage notes

  • Metric: BMI = kg / m²
  • Imperial: BMI = lb / in² × 703
  • A common healthy range is between 18.5 and 24.9.
