We don't have the metric system here fully yet (but they are trying) just a big mish mash of everything to make things interesting.

All road signs/car speedos are in miles not kilometres, but maps are generally scaled in kilometeres (how far do we have to go? - No idea).

I learned metric at school but everything in the shops was generally sold in pounds and ounces (and has only recently changed with lots of protest), confused the hell out of me when i was a kid. My kitchen scales are pounds and ounces but most newer recipes are in metric and not all provide a conversion - cue lots of mental arithmetic and a hybrid of measurements, imperial for dry weights and metric for liquids (things still seem to work).

And u's definitely belong in lots of words (colour etc, looks daft to me without it) and ize instead of ise really winds me up for some reason (daft - yes I am). The latter is only cos that's what I'm used to.
