@thomasfuchs A week or two back https://petersmagnusson.org/2009/09/15/why-are-there-5280-feet-in-a-mile/ was linked from HN on the origin of the mile; Yours had some I'd not seen - the Shaftment in particular.
For future reference: that big diagram of imperial unit length measurements is from

Actually not.. the roughlydaily one is just a badly rendered 406x600 PNG of this Wikimedia SVG https://upload.wikimedia.org/wikipedia/commons/9/9e/English_Length_Units_Graph.svg

@thomasfuchs well, to be honest, the imperial units are more human comprehendable. An inch is a finger's size, a foot around the size of a foot, a mile the distance of 1000 footsteps.
Like the pound is around a handful and the Elle is a long arms length.
It makes sense in some way. But well...
