Units problem (hiding units)
Units problem (hiding units)
(OP)
People hi!
Back from recovery.
I was wondering is there a way that you can somehow hide units from a defined variable?
Plase look at the file attach.
Variable fck has units defined.
Later on in calculation there is a coefficient (should be unitless) that uses fck value.
Is there any way that this coefficient result could be without units?
Now its using fck units and I could write the equation as in units2 file attached.
Any more sophisticated way?
Thanx

Thanx anyway

BTW, I replied to this thread yesterday with an attachment but that post seems to be gone.
Anybody an idea how and why??

blah*(fck/psi) = desired answer
any new value of fck can be used with whatever units you wind up with, since Mathcad will do the conversion transparently, i.e., you can use fck with Pa, or whatever. This automatically eliminates the multiple copies of empirical equations configured for different unit systems.

Except of course, x DOES have units!
The empirical expression as presented in the source document will only be valid as long as all of the factors are given in the correct units. One of Mathcad's strongest features for me is that it makes such empirical factors "transparent", AND it means you can use whatever units are convenient for you.
(Some people are "Grammar Nazis" - I admit that I am one, but I also have a passionate hate of empirical equations which use "dimensional" factors in Codes and Standards!)
