For additional confusion's sake, I got it wrong - It's not an "Imperial" ton in the US, but a "Customary" ton. There's also a British "Imperial" ton, and sometime called the "Long ton" (whereas the US Customary unit is also called the "Short ton". The Imperial Ton is 2240 pounds, which if you're dyslexic is the same as the Metric Ton's 2204.6 pounds.
Don't forget the metric fucktonne, as well.
