What is the formula to calculate Body Mass Index (BMI) using weight in kilograms?

The formula to calculate Body Mass Index (BMI) using weight in kilograms is defined as the weight in kilograms divided by the height in meters squared. This mathematical formulation provides a simple way to assess whether an individual has a healthy body weight in relation to their height. The relationship is established because BMI serves as an indirect measure of body fat, helping to categorize individuals into different weight classes such as underweight, normal weight, overweight, and obesity.

Using this specific formula (weight in kg divided by height in meters squared) allows for a standardized assessment applicable across various populations. The metric system provides clarity and ease of use, as it uses whole numbers that can be consistently measured and calculated.

The other choices incorporate either incorrect mathematical relationships, different units, or adjustments for weight measurements in pounds, which are not relevant when calculating BMI with kilograms. This understanding is critical for accurately interpreting body mass in a health context.
