Formula or method
BMI = weight in kg divided by height in metres squared. The broad adult screening category is then shown alongside the value.
Worked example
A person who weighs 70 kg and is 170 cm tall has BMI approximately 24.2.

Does BMI alone indicate whether I am healthy?
No, BMI is a limited screening number and should be evaluated with other health information.
