Body Mass Index (BMI ) is a measurement of a person’s weight with respect to his or her height. It is more of an indicator than a direct measurement of a person’s total body fat. Learn how to figure out your BMI , the risks of having a high or low one, and why this number can be an imperfect measure of overall health. Body mass index ( BMI ) is a screening tool based on your body weight. It’s calculated by dividing your weight in kilograms by your height in meters squared. BMI isn’t an accurate measurement of body composition. So it provides a limited view of your body fat or your overall health. Body mass index ( BMI ) is a value derived from the mass (weight) and height of a person. The BMI is defined as the body mass divided by the square of the body height, and is expressed in units of kg/m 2, resulting from mass in kilograms (kg) and height in metres (m).
