Re the ignition points gaps with the engine running better with 12 thou as opposed to 15 thou. Is this not why we started using "Dwell Metre's" ?

Ah but that was not the point i was making. When the advance/retard mechanism in the distributer moved the plate on its axis. The points opened up way too wide, cannot remember exactly, but enough to cut the power. After fitting a brand new scrap yard one it was ok at 15thou. Dwell meters & strobe lights. Brings back memories.

That would have upset the metre of the sentence….

I once had a reprint copy of Mueller's 'Treatise of Artillery' of 1791. I think he had a very substantial table of conversion factors between English, French, Prussian, Austrian etc. weights and measures. Life in his time when working with multinational equipment must have been of nightmarish complexity by comparison.

Vershoks and arshins, anyone? They're not Klingon, you know…

Interesting discussion about tape measures, I got sick of trying to use one side of the tape so I bought a couple of tapes from the USA that are only in inches and on a trip to Holland I got another tape that is only in meters (Dutch spelling)

Duncan Webster posted earlier about torque and work, but got it the wrong way round. Imperial torque is conventionally expressed in the UK as lb.ft, or more completely lbf.ft. Work is conventionally expressed as ft.lb.

I acknowledge that the Americans sometimes do it the other way round, but they are of course wrong!

As am I, that will teach me to rely on Wikipedia as a check

There was a time when a billion was a million million, but now it is a thousand million.

A Billion here, a Billion there, however you count it – there was a time when that was a lot of money.

These days it seems to be small change…(until you need to pay it back of course)

I seem to recall having worked with some of those guys, didn't have a good opinion of them….

Yes, back around WW1 dreadnought battleships cost about £1M – better value than armoured cruisers at c. £800k. HMS Hood was hugely extravagant at over £2M.

Today's capital ships are about 1500 times as expensive per aircraft carrier at £3Bn-odd a throw (I dunno if 'they' want to tell us the real figure, or even really know themselves…) – much more for the even bigger American jobs.
