What I want to do: I am making my own application. Example on a simple equation P= F/A
F variable must be kg and A variable must be cm2 and the result P will be bar or kg/cm2
thanks in advance...

Just multiply values by 1_unit:

(For example):

Code:


f:=5; a:=1;
f:=f*1_kg;  a:=a*1_cm^2;
p:=f/a;

p = 5_(kg/cm^2) {Don't use reserved variables!}
