I learnt to use both. I can buy a New Holland tractor built in England. Most parts are built in Europe ,yet they use 3/8" UNC bolts for the exhaust manifold , etc and most of the hydraulic fittings are ORFS which is a flat faced Jic thread. We have a Manitou telehandler that has BSP spool blocks etc and they use couplings to convert it to metric . I wish they would use imperial as it is easier to work with and understand.

Also I wouldn't call the thread "English vs American". The English had there own system using with things like BSF, British Standard fine which was similar to UNF. What fucked the system up was "Eurogods" telling us we could not use Imperial and had to use metric and now they say use what you want because it didn't work. Without the Euro law we would have still be on BSP.
