Calculate Body Mass Index (BMI)

What is Body Mass Index (BMI) and how is it calculated?

For calculating Body Mass Index (BMI), the weight of the person is divided by the:

a. Square of the weight

b. Square of the height

c. Square root of the height

d. Square of the sum of height and weight

Answer:

The Body Mass Index (BMI) is calculated by dividing a person's weight in kilograms by the height in meters squared. The correct option for this calculation is b. Square of the height.

The Body Mass Index (BMI) is a useful measure of overweight and obesity. It is calculated by dividing a person's weight in kilograms by the square of height in meters. The exact BMI is expressed as kg/m². For this calculation, the weight should be measured in kg and height in meters. So, the correct option in this case would be b. Square of the height.

The formula for BMI calculation is BMI = weight(kg) / [height(m)]². For example, if your weight is 68 kg and your height is 1.75 meters, the calculation would be: BMI = 68 / (1.75)² = 22.2 kg/m². The BMI is used as a relatively simple, inexpensive, and noninvasive surrogate marker for body fat. However, it doesn't consider muscle mass, therefore it might not apply perfectly to all individuals, especially those who are extremely muscular.
