How does the Ideal Weight Calculator work?
It applies this displayed method: Devine, Robinson, Miller and Hamwi formulas add sex-specific kilograms for each inch over five feet. Values stay in your browser and are not submitted to a server.
What should I check before using the Ideal weight result?
Inputs use the units shown beside each field. Intermediate values retain precision; displayed values are rounded for readability. This is a general adult estimate, not a diagnosis or personalised medical advice. Seek a qualified clinician for health decisions.
