Ideal Weight Calculator: What It Calculates
Ideal Weight Calculator gives a numerical reference from the measurements or dates supplied. The method and the quality of the inputs matter when interpreting the result.
The Formula or Method
The Devine ideal-body-weight reference uses 50 kg + 2.3 kg for each inch over 5 ft for men and 45.5 kg + 2.3 kg for each inch over 5 ft for women.
Use the result carefully
For health-related decisions, use the result as educational information and discuss important or unexpected results with a qualified healthcare professional.
