What is BMI?

BMI stands for Body Mass Index. It is a simple number. It is calculated using your height and weight. Doctors use it worldwide. It helps check if your weight is healthy. A normal BMI means a healthy body. A high BMI means risk of disease. A low BMI means you may be underweight.

BMI Formula — How is it Calculated?

The BMI formula is simple. There are two versions.

Metric Formula: BMI = Weight (kg) ÷ Height (m) × Height (m)

Example: Weight = 70 kg. Height = 1.75 m. BMI = 70 ÷ (1.75 × 1.75) = 70 ÷ 3.06 = 22.8

Imperial Formula: BMI = (Weight in lbs ÷ Height in inches²) × 703
