What is BMI?
BMI (Body Mass Index) is used to approximate your percentage of body fat. It is also used to determine if your weight could be putting you at a higher risk for health problems.
How is BMI calculated?
BMI is calculated by taking your weight in kilograms and dividing by the square of your height in centimeters.
Imperial Formula: BMI = (weight in kg) / (height in m)^2
Eg: 70 kg, 175 cm (1.75 m) => 70 /(1.75)2 = 22.86
If you prefer English units then you can take your weight in pounds times 703 and divide this by the square of your height in inches.
Metric Formula: BMI = (weight in lbs) * 703 / (height in inches)^2
Eg: 180 lbs, 5′ 10" (70") => 180 * 703 / (70)2 = 25.82
BMI Weight status categories:
Below 18.5 - Underweight
18.5 -24.9 - Normal
25 - 29.9 - Overweight
30 & Above - Obese
