Ideal Body Weight API
Ideal body weight and clinical body-metric maths as an API, computed locally and deterministically. The ideal endpoint computes ideal body weight from height and sex by the four standard formulas — Devine (the clinical standard for drug dosing), Robinson, Miller and Hamwi — each adding a per-inch increment for every inch above 5 ft, plus their average; a 5 ft 10 in (178 cm) man comes out at 73.0 kg by Devine. The adjusted endpoint computes the adjusted body weight used to dose drugs in overweight patients, ABW = IBW + 0.4·(actual − IBW), from height, sex and actual weight. The bsa endpoint computes body surface area — central to chemotherapy and cardiac-index dosing — by the Mosteller (√(height·weight/3600)), Du Bois and Haycock formulas, so a 180 cm, 80 kg adult is about 2.0 m². Height is accepted in centimetres or inches and weight in kilograms. Everything is computed locally and deterministically, so it is instant and private. Ideal for digital-health, EHR, pharmacy, clinical-decision-support, telemedicine and medical-education app developers, dosing and body-metric tools, and health software. These are clinical estimation formulas, not a substitute for professional medical judgement. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is ideal/adjusted weight and body surface area; for body-mass index use a BMI API.
