How is BMI calculated?
For metric measurements:
BMI = weight (kg) ÷ height² (m)
Example: A person weighing 65 kg
with a height of 1.70 m has:
BMI = 65 ÷ (1.70 × 1.70)
= 22.49
Important:
BMI is a screening measure and does not
directly measure body fat or diagnose a
health condition. The adult categories on
this calculator should not be used to assess
children or teenagers. Individual factors
such as age, muscle mass and other health
considerations may affect interpretation.
