What is the formula for calculating BMI?

The formula for calculating Body Mass Index (BMI) is weight divided by height squared. This means that to find BMI, you take a person's weight in kilograms and divide it by their height in meters, which is squared (height multiplied by itself). This approach allows for an evaluation of body fat based on an individual's weight relative to their height, providing a simple measure that helps assess whether a person is underweight, normal weight, overweight, or obese.

Understanding BMI is important in health and fitness contexts as it serves as a quick screening tool to categorize individuals based on their body weight and associated health risks. The other combinations of weight and height do not represent the established BMI formula, hence they do not produce meaningful or accurate assessments of body composition.
