What is the measurement system used by Calibre in output for the various formats? And, are there limitations we should know about? (like, mobi doesn't like 1.0em and 1.5 em indents - it rounds the second [or maybe truncates?]) one. And, can it be configurable?

Because I think I want my css to work like:

body{typesize:1em}
myypestyle1{typesize:76%}

This way I can change the whole size of everything by just changing the body typesize, but keep the same proportions. Without having to do math (again).

And, as long as I'm asking stuff:
On the typesize-selector mechanisms in the reading softwares; is there a way to predict what base size hits where on the scale?

For example, on a Reader, does a base point size of 12pts comw in at sm,med,lrg,xl,xxl?
