That's what you get when you suddenly switch from imperial to metric 🤷. It's a bit more "tidier" (from what I know) in the US. They started putting up distance signs with both miles and km in some states, so people get a general idea of how they correlate to each other... which is good I guess. I mean, most of the world has a general idea how to convert a mile to a km (it's 1.6, but I use 1.5 to get a general ballpark figure), while only military personnel over there have an idea of how much of a distance a km is.
They still measure weight about anything flesh or food related in pounds though.
Canada did a sudden change and adjusted pretty well. Moved here recently and they're pretty consistently metric, though I see some use of Fahrenheit every so often, though I think that's by virtue of being close to the US.
