Siam Addict Posted May 29, 2022 Share Posted May 29, 2022 15mm and half inch, 22mm and 3/4 inch pipes are very similar and fitters still use imperial terminology so technically if a fitter requests 1/2 inch he would get 15mm. Same as waste pipes are still refered to as inch and a half but on the pipe it states 40mm. inch and a quarter is a 32mm pipe. As far as I'm aware the plumbing was changed in the early 70's in line with currency. 1 Link to comment Share on other sites More sharing options...
Butch Posted May 29, 2022 Share Posted May 29, 2022 Odd really, having worked on old Fords a size 10mm and a 13mm spanner was often all that was needed, even on Escorts built in the late 60's, but then again many were built in Germany hence a standardisation I guess, When ordering stuff like fuel lines, it's always the internal diameter in mm, even for really old stuff. Plumbing is an interesting one, never knew that it was such a mix of imperial and metric, even today. Is pipe length still ordered in feet or meters?

coxyhog Posted May 29, 2022 Share Posted May 29, 2022 I always worked on British aircraft which in common with the US were always AF spanner sizes as opposed to metric.Apart from the BAe ATP which had a mix of Whitworth & AF,because half of it derived from the old Hawker Siddeley 748. It was handy when I got my Harley. 1 Link to comment Share on other sites More sharing options...
Painter Posted May 29, 2022 Share Posted May 29, 2022 The modern 6mm dowel is actually 6.35mm in diameter. I wonder why....? Probably the same reason 9mm dowel is actually 9.5mm 1 minute ago, coxyhog said: I always worked on British aircraft which in common with the US were always AF spanner sizes as opposed to metric.Apart from the BAe ATP which had a mix of Whitworth & AF,because half of it derived from the old Hawker Siddeley 748. It was handy when I got my Harley. Similarly, I had a set of imperial tools I kept on the boat to work on the original Lister engine. When that died we went to a modern revvy European diesel (it was cheap!), and had to buy a new set of metric spanners. 1 Link to comment Share on other sites More sharing options...

So if you go into a plumber merchants and ask for a length of inch and half waste pipe you would get a 3 meter length of 40mm pipe. 1 Link to comment Share on other sites More sharing options...

fygjam Posted May 29, 2022 Share Posted May 29, 2022 More importantly, do you want a 20 cm dick or a measly 8 inches? (I say "want" because I'm sure nobody qualifies yet). Link to comment Share on other sites More sharing options...
