PSI units in parameters

[andrewiv]

Correct me if I'm wrong, but isn't PSI supposed to equal pounds divided by inches squared?  If it is then why is it that inventor won't accept an equation that divides lbmass by in^2?

PSI is a measure of pressure, which is expressed in units of FORCE per unit area.  You're trying to use MASS per unit area.

Thank you.  I must need more coffee this morning.
