User-Defined Units
The Equation Library provides four user-defined units: “gmol”
(gram-moles, mol), “Ibmol” (pound-moles, approximately 454
mol), ‘"rpm” (revolutions per minute, 1/rnin), and “dB” (decibels,
dimensionless). You can use their menu keys as typing aids. To fully
use these units, add them to the custom menu. (User-defined units are
described on page 10-14.)
