📖 Deep Dive: Ideal Weight Calculator
Where ideal weight comes from
The idea of ideal weight first appeared in the 1970s. The Devine formula was originally designed to calculate drug dosages, then became widely used for health assessment. Later scholars such as Robinson, Miller, and Hamwi proposed their own revised versions.
Differences between the four formulas
Take a 170cm man as an example: Devine about 65.9kg, Robinson about 64.9kg, Miller about 64.5kg, Hamwi about 68.0kg. The differences come from their base weights and per-inch increments, usually 2-4kg apart.
A more practical reference: the BMI range
The WHO recommends adults keep BMI between 18.5 and 24.9. Converted to weight that is a range rather than a single point; for 170cm a healthy weight is roughly 53.5-72.0kg. This range better accommodates different body types and muscle mass.
