111 lb to 150 lb

These formulas give a single number from height and sex only; they ignore age, frame size and body composition, and the Devine and Robinson formulas were published for estimating medication doses. Treat them as rough estimates. For adults, the CDC counts any BMI from 18.5 to 24.9 as a healthy weight.
