BMI is the ratio of a person's weight to _____.

• A. Body fat percentage
• B. Gender
• C. Height
• D. Age

Answer: (C)

BMI is a quick measure that relates how much a person weighs to how tall they are. The formula uses height in the denominator and squares it, so the number reflects weight relative to stature. This means the ratio is weight to height, not to body fat, gender, or age. In practice, BMI helps flag underweight, normal weight, overweight, or obesity and gives a rough sense of health risk tied to body mass. In metric terms, BMI = weight in kilograms divided by height in meters squared (and in customary units, weight in pounds divided by height in inches squared, multiplied by 703).
