Observation as a Canadian: Until the US decides to finally convert (e.g. never), the rest of the anglo-sphere will be forever stuck in an awkward inbetween zone anyways. We supposedly converted to metric in the 70s but it's only ever been half-hearted, as many trades (especially construction) continue to work in imperial measurements, and most people work in an awkward combination of the two. As Canadians we typicall…
I’m American and feel like I live in the “in-between” too. I measure people in ft and lbs. I measure wood in ft and inches. I design 3D objects in cm and mm unless I’m building in wood, in which case I’m back to feet and inches. I measure speed in miles per hour. I use tools mostly in metric but sometimes in SAE (depending on where it’s made and what it is).
Basically it all comes back to the construction trades. If you own a home, and tools to work on it... you're stuck with imperial.
