Yep but thats 0.7 of an inch which isn't 0.75 but its not about the actual size its saying that ½inch pipe has a 3/4 inch id which it doesn't. Can't we stick on old measurements for imperial discussions. :p:p


:D:D:DIt's 0.734" id which makes it closer to 0.75" than anything else

Grudgingly because this thread could become boreing (yes deliberate). :D

Boring yes to most, but the reason I came in was when Keith mentioned 1/2" "iron pipe". Almost all folks not in the know would expect this to be 1/2 od, not almost 3/4" bore, making the comparison with old imperial 1/2" copper lets confusion set in.
Even worse when you consider imperial 1/2" copper was measured in actual i/d and it's replacement metric 15mm by o/d

and now it has. Have a beer. :beer:

Sorry for posting within your quote, that individual quote bit escapes me.
