Frequently asked questions
Which number should I aim for?
Anywhere in the healthy range is fine. The formulas give single points for reference — muscle, frame size and age all affect what's right for you.
Why do the formulas differ?
They were developed decades ago from different data, mainly for medication dosing, so they give slightly different answers.
Can this replace a doctor?
No. This tool gives general estimates and self-checks for information only. It does not diagnose anything. Please see a qualified health professional for medical advice, and seek urgent care if you feel unwell.
