Ok, that makes sense.

I meant, there is probably a source that says that e.g. standard parts should
be written with a staff height of 20 pt (and 7 mm is just a rounded conversion)
or it says that they should have a staff height of 7 mm (and 20 pt is the
rounded conversion). So for further conversions (e.g. to inch) I could use the
original one, in order not to accumulate the rounding errors. (I know that
those numbers are not intended to be precise to the 10th digit.)
