Rob, The biggest stumbling block is getting our American colleagues to stop using their Imperial (and modified Imperial) measures, AF screw threads & cups in the kitchen and switch everything to SI units.
At the same time we need the Gov't here in the UK to switch from miles, miles per hour, miles per gallon and pints to Km, Km/h, Litres / 100Km and half litres (it's only 68ml short of a pint). I'm old enough to know pounds & ounces, inches & feet, grammes, kilogrammes, centimetres and metres so a switch to the full Metric system won't bother me. After we achieve that we can then consider the millis vs centis vs kilo vs mega order of magnitude problems. But it's a minor problem when we have the Luddites who won't use the nice weights and measures that the French invented for us. Regards, Dougie
