Important context: These formulas were developed for drug dosing calculations, not as health targets. A healthy weight depends on body composition, fitness level, genetics, and many other factors. The BMI healthy range (18.5–24.9) is generally preferred by modern clinical guidelines. Use these as one data point among many.
