Quetelet Index
The Quetelet Index, now known as the Body Mass Index (BMI), is a simple numerical measure of a person's thickness or thinness, allowing health professionals to discuss over and under-weight problems more objectively with their patients. The Quetelet Index is calculated by dividing a person's weight in kilograms by the square of their height in meters.
