Unkown unit of piston and rod area

Unkown unit of piston and rod area

Unkown unit of piston and rod area

Hi again,
Can anyone please shed some light on a unit of area I've not seen before?  I'm using a software called FluidSim to simulate various pneumatic circuits.  When I open the dialogue box to adjust a double acting cylinder's parameters, I see the units of piston and ring area as "qcm" (see attachment).  In the pull down tab, you can also select "qmm" and "qin".  
What's funny is that when I read the help file (see attachment), it says nothing about this unit, and in fact tells me that the adjustable parameters is actually the diameter.
Googling, I found something about an ancient Roman unit of area called the quinaria, but not sure exactly how this relates.
Any help is appreciated.

RE: Unkown unit of piston and rod area

I'm sure it is German base where q stands for the word "Quadrat" which means square. So, "qcm" are cm² and "qmm" are mm² and qin means sqaure inch.  

RE: Unkown unit of piston and rod area

Ask the company from whom you bought the software.


RE: Unkown unit of piston and rod area

Thank you, micalbrch.  "Quadrat" makes sense.  Learning Latin (quinaria) and German (quadrat) during Fluid Power in my college technician course, haha.
Thanks again.
