BMI Calculator

BMI stands for Body Mass Index.

Simply put, it is an approximate indication of whether you are within a healthy weight range for your height.

The BMI formula is your body weight (kgs) divided by the square of your height in metres. Calculating your BMI is a useful way to get an idea of where you stand, relative to the ideal weight range for your height.

Knowing your BMI is important. If your weight increases or decreases outside of your ideal range, your health risks may increase.

The BMI formula is a useful measurement for most people over 18. However, some factors such as age, gender, ethnicity and physical considerations such as a high muscle mass, also play an important part in identifying a healthy weight for you. Speak to your healthcare professional to help identify whether or not you are within a healthy weight range, or what is a suitable weight for you.

The BMI formula is:

BMI   =  Weight in (kg)
Height x Height (m)
