Which ideal weight formula should I use?

The Devine formula (1974) was originally created for medication dosing. Robinson (1983) and Miller (1983) are more commonly used today. The healthy BMI range (18.5-24.9) provides the most evidence-based target weight range.

What is adjusted body weight?

Adjusted Body Weight (ABW) = Ideal Body Weight + 0.4 × (actual weight − ideal weight). It is used clinically for obese patients to calculate drug dosages.
