How to read your result

BMI places your weight into broad categories that correlate with health risk at a population level. If your result is outside the normal range, consider it a prompt to discuss your overall health, body composition and habits with a professional rather than a definitive verdict.

Worked example

Suppose you are 175 cm tall and weigh 75 kg, using metric units.

  1. 1.Convert height to meters (175 / 100)1.75 m
  2. 2.Square the height (1.75 x 1.75)3.0625
  3. 3.Divide weight by height squared (75 / 3.0625)24.5

Result: Your BMI is about 24.5, which falls in the Normal weight category.
