What is the formula used to calculate Body Mass Index (BMI)?

The formula for calculating Body Mass Index (BMI) is derived from the relationship between a person's weight and height. The correct formula is weight in kilograms divided by height in meters squared. This means that to determine a person's BMI, you first square the height measured in meters and then divide the weight in kilograms by this value.

Using this method helps standardize the assessment of body weight relative to height, allowing for comparisons across various individuals and populations. A higher BMI generally indicates higher body fat, which can be associated with increased health risks. The formula reflects this important relationship, emphasizing that both weight and height are crucial components in calculating a person's BMI accurately.
