I'm a joiner (carpenter) and when I was an apprentice I was taught in imperial.....feet and inches......whilst on sites, but taught in metric.......metres and millimetres......when at college. So luckily I can convert to both.
In the UK we are supposed to now use metric under EU laws, but the road signs are still all in miles and yards.....yet the shops sell in metres, litres and kilograms. No wonder everyone over here is confused!
On the golf course, though, everything is still imperial, so I work out my 7 iron, say, to about 150-160yd.
