------------------

It is not universal in the US.  I prefer to use knots in faster planes like the 
KR.  In slower planes like my SuperCub, I often times use MPH for speed as most 
others flying the slower planes seem to as well.  I put in the reference in 
emails and figure people are smart enough to interpolate into their choice of 
units.  But I always keep the units in my various GPS maps set to knots.

FWIW, I think it's sometimes an ego thing.  People like to use the bigger 
numbers cause it makes them sound faster.  I'm surprised they aren't all using 
kilometers for their aircraft speeds.  :o)
