Adult BMI Calculator
One measure commonly used to measure overweight and obesity is the Body Mass Index (BMI). The BMI is a relationship between weight and height that is associated with body fat, nutritional status and health risk.
BMI is determined by your weight in kg divided by your (height in metres)2.
For adults over 18, a healthy BMI is between 18.5 and 25. A result below 18.5 indicates that you may be underweight. A figure of or above 25 indicates that you may be overweight. (World Health Organisation figures 2000).
