Can I use this BMI calculator if I am very muscular or athletic?

No, BMI does not distinguish between muscle and fat mass, so highly muscular individuals may be misclassified as overweight or obese despite low body fat.

Does the NHLBI tool support metric units like centimeters and kilograms?

Yes, the calculator explicitly supports both standard units (feet/inches, pounds) and metric units (centimeters, kilograms) for height and weight inputs.

Is the BMI result the same for men and women according to this tool?

The tool states its BMI category ranges apply to adult men and women, though some health guidelines may differ by sex; the calculator itself uses the same formula for all users.

Will the NHLBI BMI calculator tell me my ideal weight range?

It provides BMI category ranges (underweight, normal, overweight, obese) based on your height, which can be used to estimate a weight range associated with a normal BMI category.
