If the US do go ahead with metrication, it should learn from our mistake, do it quick and clean, don't draw it out over a long period.
In particular, I have heard that the auto industry would have a terrible time retooling to work in a metric system.
You couldn't do them all overnight.
The next day all traffic signs were changed and the cars were driving on the right side of the road like their neighboring countries.
Also: the metric system is way more scientific than the uk/us system.Only thing I'd like to see changed is that two perpendicular lines should make a corner of 100 degrees, and not 90 degrees as it is now...

For the benefit of international readers...In the UK we are fully metricated in schools (teaching metres, kilograms, etc.) - and have been for 30 years or more. In everyday life we seem to be metricated with the exception of pints (beer, and sometimes milk), miles/yards (road distances), and fuel economy which is miles-per-gallon despite the fact that petrol (gasoline) is sold in litres!Pounds (weight) persisted in food-retailing for both greengroceries (and other loose produce) and jars (e.g. 1lb jars of jam/honey) until 5-10 years ago. For quite a while these have still been sold as 454g and suchlike, but I think gradually as packaging becomes redesigned, they will go properly metric.Of course we do have a serious issue with tools, which need to be sold using the units they actually are, because in precision engineering the difference between the true imperial size and the metric 'equivalent' (to say 2 decimal places) really does matter when you're trying to make a press fit, or a screw thread or similar. A 3/16th inch drill would actually be 4.7625mm, which is different from "4.8mm" which you might see. For legacy reasons therefore, certain tools therefore need to be available (and, to avoid confusion, sold - despite the law) in both true-imperial and true-metric sizes.(Be aware also that a US gallon -and pint- are smaller than their UK/Imperial namesakes.)
However, the UK does not appear to have adopted the common European practice of using commas as the decimal point and periods (full stops) as thousands delimiters. Is this not a potential source of great confusion?
