Theme week! Odd old units of measure. Though this one is still regularly used:
cord (KORD) - (N. Amer.) n., a unit of dry volume measure (cd.) for firewood equal to 128 cubic feet (3.6 cu. m) of wood cut for fuel and stacked "well-stowed."
A stack 8 x 4 x 4 feet, or any other combination that gives the same volume. The term is used in a few other places, but that's the legal standard in the US and Canada, and routinely used in places where heating by firewood is common. So called because it used to be measured with a cord of rope.

Thanks, WikiMedia!
