Devine (kg): for men \( IBW = 50 + 2.3 \times (inches - 60) \);\n for women \( IBW = 45.5 + 2.3 \times (inches - 60) \). Hamwi (lb): men \( 106 + 6 \times (inches - 60) \), women \( 100 + 5 \times (inches - 60) \); convert to kg by dividing by \(2.20462\). Robinson (kg): men \( 52 + 1.9 \times (inches - 60) \), women \( 49 + 1.7 \times (inches - 60) \). Miller (kg): men \( 56.2 + 1.41 \times (inches - 60) \), women \( 53.1 + 1.36 \times (inches - 60) \). BMI midpoint: \( IBW = 22 \times H^2 \) where \( H \) is height in meters. Healthy BMI range: \( [18.5 \times H^2,\; 24.9 \times H^2] \). Adjusted Body Weight (ABW) (when actual ≥120% of IBW): \( ABW = IBW + 0.4\,(W_{actual} - IBW) \).
