The formula for calculating body mass index (BMI) is correctly represented as weight in kilograms divided by height in meters squared. This formula is fundamental in assessing whether an individual has a healthy body weight for their height.

In more detail, BMI provides a numerical value that can help categorize individuals based on their body weight relative to height. By squaring the height (measured in meters) and then using that value to divide the weight (measured in kilograms), the BMI calculation effectively normalizes weight according to the proportionate height, allowing for a more standardized assessment of body composition across different individuals.

This approach is widely used in healthcare as a quick screening tool to identify potential weight-related health issues. It's important because the simplicity of using only weight and height makes it accessible and practical in various clinical settings.

The other options either misplace the units or the operations in such a way that they do not conform to the standard scientific method of calculating BMI, making them invalid for proper assessment.
