Last Updated:

This question tests a core concept of human nutrition: Adult BMI is calculated as body weight in kilograms divided by the square of height in metres: kg/m². Understanding this relationship helps explain how the body obtains energy, builds tissues, maintains immunity and prevents deficiency disease. The correct answer is Weight in kg divided by height in metres squared.

AWeight in kg divided by height in metres squared
BHeight in cm divided by weight in kg
CWeight in kg multiplied by height in metres
DWaist circumference divided by age
Correct Answer: Weight in kg divided by height in metres squaredYour Answer: A

Explanation

Correct answer: Weight in kg divided by height in metres squared. Adult BMI is calculated as body weight in kilograms divided by the square of height in metres: kg/m². BMI is a screening measure of weight relative to height, not a direct measurement of body fat or individual health. The other formulas do not produce the internationally accepted BMI unit or interpretation.
