IBW Formula Comparison (Devine · Robinson · Miller · Hamwi)
All four classic reference-weight formulas computed side by side, with the spread between them made explicit.
At most heights the four classic formulas disagree by several kilograms — the spread output makes that visible. Clinicians pick one per protocol (Devine dominates pharmacokinetics); for everyone else the disagreement is the real lesson: single-number 'ideal weights' are conventions, not biology.
