In which units is BMI typically measured?

Body Mass Index (BMI) is a widely used indicator to assess body weight relative to height and is calculated using a specific formula that divides weight in kilograms by the square of height in meters. This means that BMI is expressed in units of kilograms divided by meters squared, hence the units of kg/m².

This metric provides a straightforward guideline for identifying underweight, normal weight, overweight, and obesity categories in adults, making it particularly useful in public health and individual assessment contexts. The simplicity and universality of this measurement have contributed to its widespread adoption in both clinical and research settings.
