Ok, now to ask the obvious. Why should a particular country change its long held, tried and tested method of measurement? Good grief the Industrial Revolution came about with a myriad of different sizes. Some of these were often so local that moving from one county to another meant that nuts made, eg. here in Staffordshire would not fit a bolt made in Warwickshire. Yet the modern world came about despite this mix and match arena :-) Leave things as they are, it works. -- ============================================== I am only human, please forgive me if I make a mistake it is not deliberate. ============================================== PLEASE DON'T drink and drive it's not clever, it's just stupid.
