The number of times ‘non construction people’ make the centimetre & millimetre mistake. They say 10 or 35 when it should be 100 or 350, can be a costly mistake for some. Was chatting about this down Express Steels recently, a customer phoned in for a beam four metres and fifty long. Of course it was cut at 4050, customer picks it up and complains that it’s too short. Customer should have asked for four metres, five hundred. The old hands down there said there was never a problem when, say, 14’6 was phoned in. Centimetres should be taken out of the system completely, they confuse matters, plus dealing in millimetres is so much more accurate.
