@tarix29 @paco @ShadowJonathan I was thinking of units for resistance (ohms/1000 feet) and resistivity (ohm-cmil/ft — it has factors of 12 and 1000 and π!). But upon looking that up I came across this: https://archive.org/details/copperwiretables100unit/page/3/mode/1up
Ohm-pounds per square mile! I'm not even sure how to think about that.
(Edit: After puzzling over it: It's Ohm-(cross-sectional area)/(wire length), where CSA is in pounds/mile. So just as Ωm²/m cancels out to Ωm, the miles multiply into square miles, but it's the area of an imaginary square whose side length is the length of the wire.)
