general tip- http://www.fallout3nexus.com/articles/article.php?id=198
1 unit in Oblivion = 1 generic unit in Max (the default), which are not inches.
this is wrong. kinda.
Actually by default, 1 max unit = 1 inch.
check for yourself. customise>units setup...>system unit scale
the actual scale representation of those units doesn't mean squat after you get into a nif/ game world, because those units(which are actually inches in max) don't correlate to our perception of how inches work in real life... ie an advlt male would be a giant if he was 120+ inches tall.
so perhaps its wise just to forget inches completely and never mind I said anything.
