>There is a long list of such measurements. It is laughable and when you study the history of how these measurements came about it is truly hilarious. Things like “short ton and long ton”. Rods and Acres.
>Historically, the ounce was 1/12 of a pound and converted to 1/16 of a pound. A nautical mile is 1.1508 miles – is that why boat trips seem longer?

gee, anytime I need some fun I´ll start the history of this thing. :)
Some weeks ago a friend of mine who knows both measures tried to explain it to me, but I can´t understand anything at all... :))
