Clinical Significance

Ideal body weight estimates reference body weight from sex and height. The constants 106, 105, 6, 5, 60, and 2.2 come from the selected lb equation and the lb-to-kg conversion.

IBW is used for reference weight calculations and is separate from PBW in this calculator set.

This page uses the reference pounds equation and converts pounds to kg; it does not calculate PBW.
