Pink Skies
Regarding the degrees and the FL - where I am we just say turn left/right heading three-zero-zero etc. and the pilot reads back the exact same thing. As for FLs we had a change just recently ( a few years back) from FL one-zero-zero to FL one hundred/two hundred etc etc. As for knots I have no idea - we generally don't have a need to control using speed.
Hope this is of use
