What Is BMI?


For over 100 years, medical professionals have used BMI to determine a person's weight category. It uses a mathematical formula by combining the weight and height of an individual to find out if the individual is underweight or overweight.

BMI is known as the obesity indicator as it helps find the same. However, the tool has attracted some criticism for causing confusion and failing to measure abdominal/waist fat while determining obesity.

Limited or lack of physical activity, poor eating habits, and lack of sleep have resulted in more people getting lifestyle diseases like diabetes, hypertension, and obesity, among others.

How To Calculate Your BMI?

Metric BMI Formula

BMI = weight (kg) / height 2

BMI is calculated by dividing weight (in kilograms) by the square of height (in meters).

For an adult with a height of 180 cm and a weight of 75 kg. Our first step needs to be to convert the height into meters. As there is 100cm in a meter, we divide our figure by 100. This gives us 1.8m.

BMI = 75 ÷ (1.8 × 1.8)

BMI = 75 ÷ 3.24

This gives us a BMI figure of 23.15.

Imperial BMI Formula

calculating your bmi

BMI = 703 × weight (lbs) / [height (in)]2

For an adult with a height of 5ft 11 inches and a weight of 155 pounds (lbs). Step one is to convert the height into inches only. There are 12 inches in a foot, so we simply multiply the 5ft by 12 and then add the 11 inches. This gives us a total of 71 inches.

BMI = 703 × (155 ÷ (71 × 71))

We do the multiplication inside the brackets first:

BMI = 703 × (155 ÷ 5041)

And then...

BMI = 703 × 0.030747867

This gives us a BMI figure of 21.62.
