Frequently asked questions
Is BMI a diagnosis?
No. BMI is a screening metric, not a medical diagnosis. It does not directly measure body fat, muscle mass, or overall health status.
Can I use pounds and inches?
Yes. The calculator accepts pounds and inches and converts them automatically before calculating BMI.
