Calculate BMI: A Step-by-Step Guide Using Centimeters

Body mass index (BMI) determines the fatness of the body, which is calculated from height and weight of a person. Although it is not a direct measure of body fat, it is the most reliable screening tool to determine body fatness. You can calculate your BMI beginning with your height in centimeters.

Instructions

• 1

  Measure your height in centimeters (cm).

• 2

  Convert the centimeters into meters (m) by dividing the centimeters by 100. For example, if your height is 170 cm, your height is 1.7 m (170/100 = 1.7).

• 3

  Measure your body weight in kilograms (kg).

• 4

  Calculate your BMI. Divide your weight in kilograms by your height squared. For example, if you weigh 70 kg and are 1.7 m tall, your BMI is 24.22 (70 kg/1.7*1.7 = 24.22).
