I can’t think of another plausible explanationI’ve been long convinced there’s a secret deep state department that exists between the US and the UK, meant to ensure all language, measurements, etc are purposely kept at “close, but not quite.”
“Ok, we’ve just invented this new widget, and I propose we call it a blippity-blap, so…blappity-blip for your side? Sound good?”
“Yes…that might work, but how about this instead? You call it blippity-blap, and we’ll call it blippity-blap…but we’ll pronounce it slightly differently, like, oh I don’t know…you say BLIP-ity and we’ll say bli-PITY, hmmmm?”
“Oh, I like that, extra confusing because it’s the same spelling and all that! Now, what’s up with these teaspoons? Is everyone in agreement that 0.07ml difference is sufficient?”
“Yeah, but say ours is 0.0024oz different.”

Although in all honesty it’s a known occurrence in countries using English systems that gained independence.
It was considered a little bit of a two fingered salute waving off overseas rule
