I'm U.S., and I'd assert that all of our informational conveyance (from language to measurements) is a confusing mashup. English is a pidgin language, and we're so accustomed to the weird mashup that it doesn't seem jarring to us sometimes to mix metric and imperial in the same context. Not defending it (because it's honestly awful), just explaining why we might not notice until it's pointed out to us.
