Andy,
Not sure what picayune is, hope you can find a doctor ....
If they are multiplied wouldn't that be OZxIn or INxOZ or OX*IN or
IN*OZ? You actually are writing OZ minus IN. (OZ-IN) I read all
these posts because I dont know much, however I did know exactly what
they mean by OZ/IN. If you had a 400 oz/in situation and wanted to
determine what that is per 2 inches, you would in fact divide by 2.
400 oz at 1 inch is equivilent to 200 oz at 2 inches.

Back atcha
