BMI calculation uses which measurements?

BMI calculation uses which measurements?

• A. Height and weight
• B. Age and height
• C. Weight and temperature
• D. Blood pressure and height

Answer: (A)

BMI is calculated using a person’s height and weight. The standard way is to take the weight in kilograms and divide it by the square of the height in meters: BMI = weight (kg) / [height (m)]^2. This creates a simple index that estimates body mass relative to height. If you’re using pounds or inches, you’d convert them to kilograms and meters first (or use a conversion factor). Height and weight are the only measurements that enter the calculation; age, temperature, and blood pressure do not. For example, someone who is 1.70 meters tall and weighs 70 kilograms would have a BMI of about 24.2, placing them in the normal range. This concept provides a quick screening tool for assessing whether a person’s body size falls into categories like underweight, normal, overweight, or obesity.
