The splendidly-named British Weights and Measures Association has called for allowing the old Imperial system to return - and about time, too! Shop assistants are always telling me that such-and-such is half a kilo and I have to ask them to speak English. They get cross because they don't know the answer and I get even crosser! And why do we have to use centimetres for small items whilst we continue (thank God!) to use miles on our road system? And whilst we're on the subject, Fahrenheit provides a much clearer description of temperatures than Centigrade. Tell me 'it's below 50' and I know to take a coat!
