In Australia, centimetres, metres and kilometres are the only measurements in general usage here (ugh I hate the spell checker here, it keeps chucking a wobbly about our 'proper' spellings lol) it's re- not er...My pet peeve about metric is our schools teaching the kids to measure with Centimeters
In industry we never use cm EVER. we use millimeter mm, meter m, and kilometer km.
A teacher told me they use cm because mm are so small kids don't relate to the units. - oh, well then best that they be lost day-one in every industry I guess!
