How is BMI calculated using the metric system?

The calculation of Body Mass Index (BMI) using the metric system involves a straightforward formula where weight is measured in kilograms and height is measured in meters. Specifically, BMI is determined by dividing a person's weight in kilograms by their height in meters squared. This method provides a standardized way to assess body weight in relation to height and is widely used in health assessments to categorize individuals into various weight classifications, such as underweight, normal weight, overweight, and obesity.

Using the metric system for BMI allows for greater ease and consistency in calculations, especially in scientific and clinical settings where metrics are commonly employed. The formula is derived from the principle that BMI correlates with body fat and can be a useful indicator of health risks related to weight. By squaring the height (in meters) and then dividing the weight (in kilograms) by this squared value, BMI provides a unit-free measure that can be compared across different populations and body types.

The other options involve incorrect units or conversions that do not align with the established method for calculating BMI using the metric system.
