It is probably either in pixels or twips.

Well, there are about 25.4 mm per inch (2.54cm/in), so 3.25*25.4=82.55

There are 72 points per inch, so 3.25*72=234

There are 1440 twips per inch=4680

There are usually either 15 or 20 pixels per inch (depending on screen settings)= 48.75 or 75
Pixels can be changed based on Windows settings: Small fonts, large fonts or custom size.

Silly question, but are you using a real-world ruler or a computer ruler?  Are you measuring on a printed version or a computer version?

Do you have access to the app's source code?  If not, check the documentation or contact the manufacturer.

I don't believe it to be twips because there are 1440 twips per inch.  Could someone provide the actual conversion formula of how they get 20.15
