They’re saying that the only way you can keep neat and easy conversions between same-dimension units is by maintaining a lot of those deprecated units such as furlongs or chains, because by removing them, now you end up with complete nonsense conversions.
I get your point but as an American I’ve never heard of converting feet to chains or furlongs? Lol sounds like pirate measurements to me
I agree that they probably don’t see much use but they’re there, along with some other pretty impressive units.
That’s not what they’re saying.
