More on the backward compatibility of the metre, this video released 7 hours ago explains it nicely: https://youtu.be/PWbfVcDcfFw?t=1039 Joseph Newton - "Cursed Units 3: The British Empire Strikes Back".

Other parts of the video highlight the insanity of inconsistent and shifting definitions of imperial units such as the mile, gallon, fluid ounce, pound-force/pound-mass, etc. It's one big damning essay against pre-metric units.
