Explaining the U.S. Measurement System

Ok, you've got a cup. That's like a coffee cup. No, a real coffee cup, not an espresso shot-thing. Ok, two of those make up a pint. What? No a pint is 2 cups. It's called a pint because it's sixteen ounces of water, which is a pound. Pound and pint are the same, somehow. I guess they just started saying it differently. Ounces? Oh, I forgot ounces. An ounce is an eighth of a cup. A fluid ounce, I mean, not a...solid ounce or whatever the other one's called. It's a unit of volume, see. Then, you've got something called a long pint, which is 20 ounces, but I'm not sure that even exists except for Guiness glasses. Anyway, OK, listen, 2 pints, regular pints, is a quart. That's 32 ounces. And it weighs two pounds, I think, but I never really tested that. 4 quarts is a gallon. After that it gets hazy. Barrels I think is the next one up, and that's like 50 gallons or something like that.
