This is not so much a "British" thing as a "German" thing, with the Din 
and ISO standards for drafting, all decimal points are replaced by a 
letter indicating the decimal point eg a 1.2K resistor is 1K2, bellow 1K 
we use an R as it is easier to draft than an omega.

I agree that it different, but it is just what you are used to.
