BMI Calculator

How to use

1. Weight in kg.
2. Height as feet and inches, or total cm if you switch the unit.

One example

78 kg, 5 ft 6 in. Height is 1.676 m. BMI is about 27.8, in the overweight band on the usual chart.

Common mistakes

• Typing 5.6 as 5 feet 6 is fine here because we have two boxes. Dont put 5.6 in cm mode.
• Athletes with more muscle look high on BMI.
• Kids need a different chart. This is adult style.
