Because it can.
when I was there, the Brits gave directions in miles... That was about a decade ago.
Uhhhh....Hey Tom.....no Brit and anyone from the UK I have ever met ever orderd a 0.89 liter of beer or ale. They always ask for a pint. Also, when you go to the fair or the ball game do you ask for a 28cm coney or do you ask for a foot long? Oh....and did Roger Bannister break the 4 minute mile or did he break the 4 minute 1.61 Km? Just asking Tom.
What is a 'foot long'?
My dick is one thing.
Methinks you should try to understand the difference between inches and centimetres.
