BMI or Body Mass Index is calculated to evaluate your body fat using your height and weight. The Body Mass Index, also called Quetelet Index, was developed by a Belgium statistician Adolphe Quetelet in 1800s. Quetelet had developed this simple measure to classify people by optimal body weight relative to the height.
Body mass index can be calculated using metric numbers. It is calculated by dividing your body weight by the square of your height. It is expressed as kg/m2. This ensures universal use of BMI.
How is BMI calculated
BMI = Weight (kg) / Height (m) ²
If your height is 175 cm and weight is 75 kg, your BMI is calculated as follows:
75kg / (1.75m²) = 24.49kg / m²
