When converting from other formats to epub (especially, but not only, AZW and KFX), there's an annoying issue with inconsistent measurements in the stylesheets. One might see something like this:
Code:
.class16 {
line-height: 1.2337em;
text-indent: 1.5em;
margin: 0 8.177348%
}
which I find annoying in two respects: Different measurement units, and unpredictable and wildly overprecise measurements imposed on a reflowable text. Are there settings available to

force all measurements to use the same units, and/or

round off/otherwise limit measurements past the decimal point in the stylesheet
during conversion? Or is this something that will always require manually editing the epub stylesheet(s), possibly because there's something in the source files that forces this sort of thing that I'm unaware of?
