How it is calculated

Compare Devine, Robinson, Miller and approximate Hamwi for height ≥ 152.4 cm. The four-equation average is author-defined; AdjBW = Devine + 0.4 × (actual weight − Devine), only when actual weight exceeds Devine.

Formula

Devine (M): 50 + 2.3 × x; Devine (F): 45.5 + 2.3 × x; Robinson (M): 52 + 1.9 × x; Robinson (F): 49 + 1.7 × x; x = height(cm)/2.54 − 60; AdjBW = Devine + 0.4 × (weight − Devine). Compare Devine, Robinson, Miller and approximate Hamwi for height ≥ 152.4 cm. The four-equation average is author-defined; AdjBW = Devine + 0.4 × (actual weight − Devine), only when actual weight exceeds Devine.

Limits of the method

These equations do not determine a single healthy or desirable weight. The AdjBW factor is not universal for nutrition or medicine dosing. Weight at BMI 18.5–24.9 is a separate arithmetic adult reference, not an individual target.
