Frequently asked questions
Which formula is most accurate?
Devine is the classic medical dosing formula; Robinson and Miller are refinements. All three give slightly different numbers — the tool shows all three.
Is ideal weight the same for everyone?
No — frame size, muscle mass, and age matter. Treat these as reference ranges, not medical targets.
