What is the formula used to calculate BMI?

Correct option is B

Sol. BMI (Body Mass Index) is calculated by the formula: BMI = weight (in kilograms) ÷ height² (in meters). It is a standardized method used globally to classify individuals into categories like underweight, normal, overweight, and obese. The unit for height must be in meters for the result to be accurate. It is used as a screening tool in clinical and public health settings.
Explanation of each option:
· (a) Weight in kgs / height in centimeter² – Incorrect. This formula will result in an inflated value, as centimeters are not the standard unit used in BMI calculation.
· (b) Weight in kgs / (height in meter)² – Correct answer. This is the universally accepted and WHO-recommended formula for BMI assessment.
· (c) Weight in kg / height in feet² – Incorrect, as feet is not a metric unit, and results from this formula would be inaccurate and non-standard.
· (d) None of these – Incorrect, because option (b) is the precise and accurate formula for BMI.
