I recently bought the screen measurement pack for Macs and have enjoyed seeing how it can be used.

My question relates to display of units.

If I set the units to say "inches" or something else, the numbers shown on any skin I've tried are just absolute numbers - there's no where on the display which can show what the unit of measurement is (that I can find.)

On my digital calipers, for example, it shows units in inches or millimeters right on the LCD display. I really need something like that, otherwise, I would need to annotate all my screens with the extra "units are in yards", or "units are in millimeters."

I'd rather have the instrument itself show the unit either on the numeric display or perhaps on the ruled slider somewhere.

Is there an option for showing what measurement units are applied?

It's currently not shown on the display. On a PC it's shown in the Taskbar, but the Mac does not have that functionality. So the easiest way is to right-click and select the units menu if you forget which one is selected.
