At senior school in the early 2000s, I was taught both metric and imperial and how to convert between them. But I have some friends who are 10 years younger than me (I'm 32, they're 22) who were never taught imperial at school. Neither knew what a 'yard' was.. probably because neither of them drive. At least things are changing!
