Title: Consistency

It was driving me insane how many different ways we converted between units at different spots.
I tested this, I read the diff repeatedly and carefully - I /think/ I didn't break anything. But please be aware that this changes quite a bit of code that does things in subtly different ways (some of them very silly, btw).
