What measurement can be calculated using the formula kg/m²?

The correct answer is based on the fact that the formula kg/m² is used to calculate Body Mass Index (BMI). BMI is a widely accepted measure that evaluates whether a person has a healthy body weight for a given height. The calculation is done by taking a person's weight in kilograms and dividing it by their height in meters squared. This formula produces a number that can be interpreted against standard BMI categories which indicate underweight, normal weight, overweight, or obesity.

BMI is a useful screening tool that helps to assess health risks associated with body weight, making it a significant measure in maintaining a healthy lifestyle. Understanding BMI provides valuable insights into potential health issues and assists individuals in making informed decisions about their weight and overall health.

Other options such as body weight, body composition, and muscle mass do not specifically rely on this formula. Body weight is simply the total mass of a person, body composition refers to the proportions of fat and non-fat mass in the body, and muscle mass indicates the amount of muscle tissue in the body. While all are relevant to health and fitness, they do not utilize the kg/m² calculation directly like BMI does.
