Ideal Weight Calculator guide
What it is for
The Ideal Weight Calculator provides a planning estimate from the information entered.
How it is calculated
Devine reference weight in kg = 45.5 for females or 50 for males, plus 2.3 × max(0, height in inches − 60). Convert the resulting kg to pounds.
Assumptions
It assumes the inputs use the requested units and represent a general reference population, not an individual assessment.
Example
For a female at 65 in, the reference is 57 kg, approximately 125.7 lb. It is a historical reference formula, not an individual target weight.
Limitations
This is an educational estimate, not a diagnosis, treatment, or dosing instruction. Consult a licensed healthcare professional, particularly during pregnancy, with symptoms, or before changing health behavior.
