Speed in the ships is measured in AU right? and AU is how many KM exactly, I remember seeing it somewhere but now I cant find it. I want to know so I can correlate a battle in space for my DW game.

No, it's measured in Void Units (VU) which are approximately 10,000km.

ok, do you happen to know where that was listed?

In space combat, the distance from one ship to another, or how far a ship moves in a Strategic Turn, is measured in void units (VUs). The distance represented by a single VU is deliberately abstract and left open to some interpretation due to space’s vast size. However, a good guideline is a single VU equals roughly 10,000 kilometres.

That's from page 213.

cool, thanks
