How is BMI calculated?

The Body Mass Index (BMI) is calculated by taking a person's weight in kilograms and dividing it by their height in meters squared. This formula provides a standardized way to categorize individuals based on their body weight relative to their height, which helps in assessing whether a person is underweight, normal weight, overweight, or obese.

Using weight in kilograms allows for consistency in calculations, especially when comparing people from different regions that may use different units of measure. By squaring the height in meters, the formula accounts for the two-dimensional aspect of body mass relative to height, allowing for a more accurate representation of body composition. Thus, the formula is ideal for general assessments of health in populations.

The other calculations based on different units or arrangements do not align with the standardized method for calculating BMI. They might produce values or units that are not recognized for clinical assessments of body weight and health, which is why they are not applicable in this context.
