Unit Of Measurement

Body mass index (BMI) is an internationally recognised standard used to classify the body weight of adults. But BMI isn’t a completely accurate measure of body fat content as it doesn’t take into account factors such as muscle mass, bone density, body composition, and racial and gender differences.

It is not an appropriate measurement for various groups, including people who are:

  • 18 years and under
  • 65 years and older
  • pregnant
  • very muscular
  • of various ethnic communities, including people of Asian, Aboriginal or Torres Strait Islander descent
  • living with a physical disability.

BMI excludes other important measurements of health, such as cholesterol, blood sugar, heart rate, blood pressure and inflammation levels. Find out more about the Body Mass Index and if it’s right for you.

This calculator has been reviewed by Bupa health professionals and is based on reputable sources of medical research. It’s not a diagnostic tool and shouldn’t be relied on as a substitute for professional health advice.
