Estimates ideal body weight from height using four published clinical formulas — Devine (1974), Robinson (1983), Miller (1983), and Hamwi (1964) — and shows the consensus average.
'Ideal weight' has no single number, and different medical traditions produced four slightly different formulas. Showing them side by side makes the range honest instead of pretending one formula is correct.

Male, 70in → Devine 73.0 kg, Robinson 71.0, Miller 70.3, Hamwi 75.0 (avg ≈ 72.3 kg)Female, 60in → all formulas converge near their base value (~45.5–53 kg)Male, 183 cm → automatically converted to ~72 in before applying the formulasQ: Which formula is most accurate? A: None
they were derived for drug dosing (Devine) or survey populations; showing all four with the mean is the honest answer.
Q: How are imperial heights handled?
A: Everything is converted internally to inches at the 5 ft + 2.3 lb/in baseline (or each formula's variant).
Q: Why do women get a different constant?
A: All four formulas were fit on sex-specific population tables.
Q: Is this medical advice? A: No
this is a statistical reference range.

Four published clinical formulas shown side by side — they span a narrow band; the mean is a reasonable single estimate. Height-based formulas ignore frame size, muscle mass, and body composition. Not medical advice. Runs locally.
