What is BMI?

Definition

The Body Mass Index (BMI) is a simple measure for assessing body mass. It is calculated by dividing body weight by the square of body height, and allows for a standardized assessment of weight to height ratio.

Formula

BMI = Weight (kg) / (Height (m)²)

Example: 70 kg / (1.75 m)² = 22.9
