Side-by-side comparison helps you choose the right calculator for a specific clinical question.
Clinical
Calculate adjusted body weight (AdjBW) for drug dosing in obese patients: AdjBW = IBW + 0.4 × (TBW − IBW). Used for aminoglycosides, vancomycin, and other weight-based medications when actual weight exceeds IBW by >20%.
Formula
ABW = IBW + 0.4 × (Actual Weight − IBW)
Inputs
Body Metrics
Calculate your ideal body weight using multiple formulas (Devine, Robinson, Miller, Hamwi). Find a healthy weight range based on your height and sex.
Formula
Devine: Male = 50 + 2.3 × (height_in − 60), Female = 45.5 + 2.3 × (height_in − 60)
