This discussion and all the confusion about different legacy measurement units used around the world and still being used in some places for some common cultural measurements is exactly the arguments why we need SI!

Do not open attachments or click on links from unknown senders or unexpected emails. I did not mean to imply that you don't know the difference, if that is how you took it. But we, the US, use US units and trade in the Caribbean with people who still use Imperial units. Due to subtle changes (eg, the inch definition in terms of SI), some of those units are not exactly what they were back in the Colonial period either. The US gallon is still 231 in³ (the old Queen Anne wine gallon), but the inch isn't what it used to be. We need to be clear that they are US units, currently defined and maintained by a US agency, NIST. I agree that US Customary is "Some Old British Nonsense" but actually calling them that adds to the potential for confusion with our trading partners and we intend to keep calling them Customary. Just as it is incorrect to call them "Freedom Units" (as some Americans do) it is silly and confusing to call the WOMBAT, obsolete British units, or any other silly name. At least, that's my view.

Customary is NOT Imperial, there are several differences. ... I know they are different. As I said, Call it "British Colonial Measure" (to distinguish it from the British Imperial system, that was a reform of 1824). I don't recommend calling it "British Imperial" as this would be factually inaccurate. I suggested "British Colonial" because it is different from "British Imperial" but calling up images of the Colonial period, and emphasising it is NOT an American system. Calling it "Customary" is OK too, but I'd recommend not calling it "US" anything, as there are too many people whose misguided patriotism will be triggered.
