True, but I bet old-school machinists can convert in their heads. They’d know exactly what 13/64ths is in thou
I predate decimalisation, but 10 doesn't fit, I wonder what the next size up is ... ohh that's right 11 is much easier than imperial.
Ah c'mon, surely everyone goes to the builders merchant and asks for 2.4m of 4x2 ? It is the British way!
I like that I’ve fitted a garden tap yesterday, backplate is 15mm to 1/2 inch . when I worked in Spain my Spanish boss borrowed my tape measure and nearly threw it back at me as it had cm and inches on he made a disparaging comment about the English that I decided to take as a compliment he should talk, I’ve never worked with so many different pipe sizes. 15,16,18,19,29,25 mm depending on material. Still use 3/8,1/5, 3/4 inch etc brass fittings too!
As far as I’m aware, tap thread sizes used by those Continental types are still Imperial (poss converted to millimetres). May even be an ISO standard, presumably because the thread sizes are useful?
Also in Spanish plumbing it’s quite common to use chest or armpit hair to seal tap fittings. Works pretty well!
Ha! Just looked it up like a saddo. It is BSP or BSPT, Whitworth thread. Take that, Johnny Foreign, with your bidets and armpits! Doesn’t apply to the US, who have a nice pipe thread of their own.
But they are all dead ! I kept loads of my old man's imperial taps, dies and spanners, lugged them around three house moves and now finally about to skip them.
Never really thought about it, but it's also true for an 8x4 sheet of 19mm plywood. I guess it comes from being an age where metric and imperial were both taught and used.
Argghhhh. You're both right, of course, but..... https://www.simscale.com/blog/2017/12/nasa-mars-climate-orbiter-metric/
Here in very decimal Switzerland, bread is often sold by the pound = 500g I've never heard of a subunit of pounds though, 'ein Pfund Brot'. I've even seen things measured in inches, or 'Zoll', especially bicycle frames for some reason. But even on the SI continent there can be the occasional misunderstanding. I work near Laufenburg, which sits on the Rhine and has a nice bridge into Germany. Whilst both the Swiss and Germans started building the bridge from each side based on heights above sea level, it was only in the middle did they realize that the Swiss use French Mediterranean sea level, whilst the Germans North Sea level, about 10 'Zoll' difference. An expensive mistake.
