BMI Calculator

Calculate adult BMI from height and weight. BMI is a screening measure and does not directly measure body fat or overall health.

How it works

  • BMI = weight in kilograms ÷ height in metres squared.
  • Standard adult BMI bands are used for the category display.
  • The tool is educational and is not a medical diagnosis.

Example

For a person weighing 70 kg at 1.75 m, BMI is approximately 22.9.
