Now THAT is an interesting information, never heard of "furlongs" before!

It's a fantastic unit if you need to convert distances from metric to imperial, because 1 furlong = ~200 meters. So if you tell someone something is half a kilometer away and they ask what that is in imperial, you can quickly respond "2 1/2 furlongs".

A furlong, the approximate distance that an average draft horse can pull a single-bottom plow before needing a rest, is my favorite measurement because it sounds so grounded in reality. It's just how long the furrow is.

Right next to the parsec, but only because of the Star Wars references :-)

Snails are rated in furlongs per fortnight.
