Well, quite probably given the official conversion is given as 112km/h. But anyway.. even if it is 70mph by statute, it turns out 112.65408km/h is exactly the same speed so it doesn't matter at all. ie: if I'm pulled over by a policeman and he says "you were doing over 70mph" a valid defence is not "no, I was travelling at 120km/h so I can't have been".
