I really don't care what unit Scribus uses internally, but if I set a paper size to A4 I would want it to be A4. Not "almost A4". Since the A series papers are defined in mm I think Scribus should use the size in mm, not use the size in points and then convert to mm. The conversion should be from the user's set values into Scribus internal units, not the other way.

I mean, If you set a page width to 10 inches, would you really like it to be changed to 9.9987 inches just because the program doesn't internally use inches?

Even if Scribus uses points interally, does it use integer points? No fractions? Using 1/10 or 1/100 pt as resolution would make rounding errors neglible.

210 mm (A4 width) makes 595.3 points (rounded). 595.3 points is 210.0 mm (rounded).
