How is Body Mass Index (BMI) calculated?

To calculate Body Mass Index (BMI), the correct formula is weight in kilograms divided by height in meters squared. This method provides a standardized way to assess body weight relative to height, helping to categorize individuals into different weight status categories such as underweight, normal weight, overweight, and obesity.

The formula uses metric units since this is the standard used in medical studies and global health guidelines. By converting the individual's weight into kilograms and height into meters, BMI can be calculated accurately, providing a reliable indicator of body fatness for most people.

While other options may present weight and height in various units, the formula that uses kilograms for weight and meters for height is the medically accepted version, making it the most appropriate choice for calculating BMI.
