Compare published adult historical reference-weight formulas with clear applicability limits and a separately labeled BMI reference interval.
01 / CALCULATION INPUTS
Adults only. These historical formulas are rough references, not individualized weight targets, medication guidance or advice to lose weight. Published sex-based coefficients do not assess gender identity, body composition or pregnancy.
02 / RESULT & SUPPORTING CALCULATIONS
Adults only. These rough historical sex-parameter estimates are not individualized healthy-weight goals, a diagnosis, drug-dosing guidance or a recommendation to gain or lose weight. They do not reliably account for body composition, pregnancy, disability or athletic build. The equation parameter is not a gender-identity assessment; no single “ideal” weight is medically definitive.

Devine 1974, Robinson 1983, Miller 1983 and the original pound-based Hamwi 1964 equations are transcribed from Table 3 of the published Peterson et al. 2016 review. Hamwi pounds are converted with exactly 0.45359237 kg/lb rather than mixed with a rounded metric variant.
It selects the coefficient set used in the original publications. It is not a gender-identity assessment or a personalized medical determination, and the calculator does not infer the appropriate parameter.
Adults ages 18–120 are supported. Formula comparisons are conservatively confined to 60–75 inches, the adult comparison interval discussed in the review. Outside that interval formula values are withheld rather than silently extrapolated.
No. It is separately calculated as BMI 18.5–24.9 times height in meters squared and is labeled as a reference interval, not an average of the historical formulas or an individualized healthy-weight target.
Yes. Optional actual weight is converted to kilograms and its signed difference from each available reference is shown. The difference is descriptive, not an instruction to gain or lose weight.
No. They are rough adult historical references and do not reliably account for body composition, pregnancy, disability, athletic build or individual circumstances. They are not diagnoses, medication-dosing guidance or prescriptive weight recommendations.
