What is BMI?

The body mass index (BMI) is a measurement of body fat that applies to adult men and women and is based on height and weight.

A high BMI may indicate a high level of body fat. BMI detects weight categories that may cause concerns to your health, however it does not determine an individual’s body fatness or health.

How do you calculate BMI?

BMI uses a basic calculation based on a person’s height and weight. This calculation may vary slightly depending if you are using the imperial system or the metric system of measurement.

Imperial BMI Calculation

The imperial BMI formula is your weight in pounds (lbs) divided by your height in inches squared, and then you multiply this figure by a conversion factor of 703.

Metric BMI Calculation

The metric system BMI formula uses kg to represent a person’s weight in kilograms and m2 represents their height in metres squared.
