          But is it? most people now accept metric as it is widely used for wood and various sizes.

          Just learn to use both standards, all white goods give metric sizing. So a DRO ihas the switch between the two, good.

            Regarding wood – I've never understood why it is sold in 1.2 mtr, 2.4 mtr lengths! I assume it is because it is impossible to divide by 3 in the 1, and 2 mtr lengths. Strange that they should decide on such an anomaly in a 10 base system.

            Likewise there is little uptake of the metric 400 grad divisions within a circle, although I have come across this weird division for circular definition in the Bosch engine management system for engine control to define crankshaft angularity – it caused mayhem before it was realised that a grad was not comparable to degrees.

              Ah, sorry, it's the news that we are to revert to imperial measurements.

                1.2 mitres = 4 feet etc. It is easier to change the numbers than the actual dimensions.

                Changing back to imperial units. You must be joking and it is not even 1 April.

                    Stuff Empire Day – Lord Beaverbrook hasn't been around for sometime……let's have a new Bank Holiday and call it Independence Day and thumb nose at the Brissels crowd.

                      I've still got the marks on the handle of the coffee spoon I pinched from my dad in 1973, where I set the magneto on my BSA A10 to 13/32" BTDC.

                      But my 2 sons and their families can't abide Imperial – they think it's deliberately arcane and difficult, which perhaps is part of its quirky charm.

                        The building industry is still a mess after all these years, a six foot fence panel is now 1800mm. Installing my new fence the concrete gravel boards were actually 6’ so the slotted concrete posts were too loose to contain an 1800mm panel, a couple of packing strips added to the panels made them fit.

                          Try getting a replacement 2' x 18" manhole cover!

                          When the galvanised steel one in my garden rotted away (taking with it into the sewer the wife's prize plant pot and contents) I was unable to buy a replacement. To get over this I had a mate with a bending machine make me up one in 2.5mm plate. The Builders Merchant told me the only way to replace these manhole covers was to fit the metric ones which meant rebuilding the top of the brickwork to suit the new cover and its frame. My mate now knocks out batches of imperial covers of 50 a time and they sell like hot cakes!

                            What I find is ridiculous is that plywood is sold as 4' x 8' sheets, and dry lining is sold in the slightly smaller metric size. It means that if you layout first floor joists for sheathing, then the layout will come up long for sheathing the ceilings below with dry lining; so you have a considerable waste loss of material when installing a ceiling.

                              Fiddling while Rome burns comes to mind. Are they going to redefine the pound as a fraction of a kilogram the same way the USA defines their inch as 25.4mm?

                                Better still the Chinese tailors Inch!

                                I had a suit made in Shanghai and when they measured me up my waist was 30" and inside leg was 27" – I was delighted that my waist had shrunk but not so pleased about the loss of 5" height! On questioning the tailor it turned out their Inch is based on 30mm!!!!

                                    500g is widely called a pound across Europe, of course it’s a pfund in Germany and many countries have a word for it. I am sure that for foodstuffs it makes little difference as long as you aren’t supplied with 453.6g and charged for 500g.

                                      Are you sure your not; & by the way I've not seen anything on sale with a weight of 453.6g it's always 100g, 450g, 500g, 1kg increments.

                                          This is going to degenerate into a stand off between die hard imperialists and rational people who can see beyond the ends of their noses

                                                I recall the 8ft (2400) length of wood was a standard supplied by the Scandinavians and called a 'deal' and as such sold throughout Europe starting hundreds of years ago. Hence houses everywhere tend to be built using submultiples of it, regardless of units used. 16in stud spacing has never been a 'round' figure that a mathematician might choose, let alone the 14+ a smidge for the noggin. It is only recently that site carpenters apart from the foreman could afford a rule anyway. As for plasterboard not fitting, that's probably 'cos some dumb ass graduate engineer who had never been near a building site wanted to make it a nice 'round' figure.

                                                  I'm 78, so older than Mick above, and I much prefer metric. Indeed, I find metric linear measurements much more understandable than imperial. Capacity measurements & weights are someway behing linear measurements, but slowly I'm getting there, and I don't want to go back. Indeed, the whole concept of imperial I find to be a recipe for disaster. Think pennies, shillings, pounds, what a rotten system requiring an in depth knowledge of the 12 times tables and the 20 times table. 100p to the pound is so much easier. Similarly, ounces/pounds/stones/hundredweights/ton's etc. requiring a knowledge of 16's, 14's, etc.

                                                  So, as far as I am concerned, although brought up as an imperial child, and am to an extent struggling with the visualization of the various metric quantities, I am slowly becoming au fait with it, indeed in some instances I already do think metric in preference to imperial.

                                                  It will be a bad day if we have to revert to imperial.

Nostalgia apart, metric is far more logical.

                                                      I do however after so many years have the ability to be able to quickly convert in my head approximations of imperial to metric and vice versa. The industrial fan industry I (still) work in deals with markets all over the world and mechanical, chemical, electrical engineers etc. all with favourite units such as cubic feet per minute, m3/hr, inches water gauge, pascal, millibar ad infinitum. There are times however when the metric system falls down, I can readily convert all these but I have always said the bloke that invented inches water gauge new what he was doing, you can see a column of water, how do you visualize a pascal? Easy, convert it to inches water gauge!!
