Body Mass Index is a person's weight in kilograms divided by the square of the person's height in metres. Thus, the unit for BMI is kg/m^2.
The good news is that one can calculate one's BMI by oneself. Helping you to keep your weight in check
The BMI is an attempt to quantify the amount of tissue mass (muscle, fat and bone) in an individual, and then categorize the person as underweight, normal weight, overweight or obese based on that value. The generally accepted BMI ranges are:
Underweight: <18.5
Normal: 18.5 - 24.9
Overweight: 25.0 - 29.9
Obese: 30 and above
Obese and overweight individuals have weight that is greater than it should be for their health. Underweight individuals have weight that is lower than it should be for their health. Body weight depends on your sex and height and for children, it also depends on their age. A sudden, unexpected change in weight can be a sign of a medical problem and this is one of the reasons why keeping your weight in check is important. It can be useful as a sign for urgent medical attention thus preventing progression of pathological conditions into chronic states.
