My condolences. I'm already annoyed with the times USC units are presented in Australia (our nominal pipe sizes are often talked about in inches, and sometimes valves and such have USC flow coefficients because the manufacturer is American).
So I cannot imagine the pain you must be subjected to.
There are three sizing standards used in the UK right now: metric for newer homes, imperial for older homes and farmer's sizing for fuck you, that's why.
We even like combining them in one thing. Tyres are measured using inches for one dimension and millimetres for the other two.
