What is Body Mass Index (BMI)?
BMI stands for Body Mass Index, which measures body fat based on a person’s weight and height. It is used as an indicator of whether a person has a healthy body weight in relation to their height. It is a widely used measure that can assess a person’s body composition and classify them into different weight categories.
BMI Calculation Formula
Actually there are two ways to calculate Body Mass Index (BMI), the first formula uses metric unites and the other uses imperial. The formula is:
BMI = weight (in kilograms) / (height (in meters))^2
BMI = (weight (in pounds) / (height (in inches))^2) x 703
For Example,
If a person’s weight is 60 kg and height is 165 cm (1.65 m), the BMI is calculated as 60/(1.65)^2 = 22.04 kg/m^2, which means that the person have a BMI of 22.04 kg/m^2, which is considered as a healthy weight.
If a person’s weight is 120 lbs and height is 66 inches, the BMI is calculated as 703 x 120/(66)^2 = 19.3 kg/m^2, which means that the person have a BMI of 19.3 kg/m^2, which is considered as a healthy weight
