    I can't help but get a faint smile, whenever I see one of these metric v Imperial debates, since, at the age of 7, I and my classmates, in a small village school, were considered capable of coping with learning both systems at the same time; why are today's schoolchildren unable to cope?

    The laugh is that I remember being told, by a Frenchman schoolteacher, that the whole metric system is based on a false measurement of the world's circumference, so a metre shouldn't be the length that it is.

    Ever wondered why water has a specific gravity of 1.0? A gallon weighs 10 lbs, and a gallon of white spirit, at an S.G. of .76, weighs 7.6 lbs.

    A mile is the distance you can walk in a quarter of an hour; market towns are an average of 7 miles apart because that was the distance an oxcart could travel in a day; the top joint of an average man's finger is 1 inch; a yard is the distance from your nose to the tip of your middle finger, with your arm stretched out to the side (makes measuring cloth a doddle.) Fancy a 10-month year? Or a 10-day week? How about working 8 hours in a 10-hour day, then? How about an hour of 100 minutes? All of these were tried, and got nowhere; just because we have 10 fingers and toes doesn't make it a natural number to use.

    Before the Witchfinder General is called out, to deal with me, I see no problem in using both systems. As an example, though, the Spitfire's wheel track is 185.4cm, or 73"; I know which I would prefer to divide by 72, should I contemplate a 1/72 kit.

      Yes, I'm smiling faintly too

      Today's children are perfectly able to cope with learning both systems, they're not a different species whatever us oldies may think, it's just pointless teaching a redundant system

      I too was taught both but only ever use decimals as they work better for me, something to do with my engineering background maybe, or maybe because measuring things by your finger-length or how far you can walk in a day is no longer relevant, harking back to the "good old days" is very satisfying but rarely helpful in my opinion

        I think the metrics win, so those are the one I got from Albion Alloys

          I voted Metric as it is,as has been said,the way of the future.

          I dispute scale being easier to calculate in millimetres. Popular modelling scales are based on the Imperial system. 1/48 is a quarter inch to a foot for example,hence often 'quarter scale' across the pond.1/72 is an inch to six feet.

          The truth is I'm of an age when I'm comfortable with both.

          Cheers

            Is that why such seemingly odd scales as 1/48 and 1/72 are used rather than, say, 1/50 and 1/100 (though I gather the latter of these used to be more popular)?

              Nothing wrong with imperial in simplistic measurement. Even though I worked for 25 year in metric at the back end of my working life I still use imperial for carpentry jobs around the house. Daft but it is printed for ever in my brain.

              But if you have worked in engineering, architecture or allied industries then in imperial you come up against massive time consuming problems. The main one is a calculator. May be there is one but I have never ever seen an imperial calculator. Metric are 10 a euro.

              Try adding up 13 window lengths at 2feet nine & four 64th inches. Then taking that away for the length of a building 87feet 3 & three 32nd inches. Then calculate from the answer in brick sizes the piers between the windows. All worked out by the brain.

              In metric you work with straight forward figures either side of the point so simple. Punch in a calculator the above in metric, job done in less than a minute. The brain is still as fresh as a daisy.

              Imperial is doooomed.

                Someone told me they were 1.85 tall the other day..... What on earth is that?

                6 foot and I can picture it, 5'8" or whatever - easy-peasy. But 1.85 in meaningless, might as well be a dwarf or a giant for all I know!

                    Yes,they are only odd if you are metric.

                    I too use both systems at work. British and European companies are all now metric and supply everything from cable lengths to steel wire ropes in that format,despite the fact that stage sizes are almost always still given in feet! A 1T hoist means one tonne not our old 20cwt ton.

                    None of the Americans I work with are metric,everything still in feet and inches for them and weights always in pounds.

                      87' 3 and 3/32" minus 35' 9 and 13/16" = 51' 5 and 9/32". If your bricks are 6" you'll need 103. If you need an imperial calculator find an old Lsd calculator, since shillings and pence are the same as feet and inches. And the brain is exercised. Took me longer to write it than to do it.

                          The problem for the old system is that whilst I,and I suspect many others on the forum,understand the Imperial system and its nomenclature if I was to show your little sum above to one of my daughters (both perfectly intelligent young women) they would have no idea what it meant. That is why,sadly,Laurie is correct and the old Imperial system is indeed doomed.

                          I wonder how long the Americans will hold out?

                            Must say this thread has been entertaining whilst on the train! Maybe changing things should have been a warning for those who chose to go euro, fat lot of good that has done!
