Ideal body weight (Devine formula).
These calculators use established formulas (such as Mifflin-St Jeor for calorie needs or the Devine formula for ideal weight) to provide general estimates. They're built for a general population and don't account for individual medical conditions, medications, or circumstances. They aren't a substitute for advice from a doctor, registered dietitian, or other qualified healthcare provider — especially for anything related to pregnancy, chronic conditions, or medication dosing.
Devine formula: 50 kg (men) or 45.5 kg (women) plus 2.3 kg per inch over 5 feet (60 in).
Used in clinical medication dosing. Not a definitive personal target — muscular or larger-framed people can healthily weigh more.
Several other formulas exist (Robinson, Miller, Hamwi) and each gives a slightly different number for the same height — the spread between them is a useful reminder that any single 'ideal weight' figure is an approximation, not a precise target.
175 cm male (~68.9 in): 50 + 2.3 × (68.9 − 60) ≈ 70.5 kg (155.3 lb).
Most cited in medical dosing. For a healthy range, BMI 18.5–24.9 for your height gives a wider, more realistic band.
No — reference point, not a target. Frame size, muscle, and composition matter more.
Each was derived from a different reference population and methodology decades apart — none is definitively 'correct,' which is exactly why doctors treat these as reference points rather than diagnostic targets.
