According to www.thefreedictionary.com/ton , a "ton" is also a unit of _volume_ in shipping -- either 35, 40 or 100 cubic feet. 35 cubic feet is approx one cubic meter. I recall from high school chemistry that a cubic foot of water is 64#, so 64*35 = 2240#, which is the definition of a "long ton".
But isn't the good ton to use here the metric ton? 1 metric ton = 10^3 kilos = 10^6 grams; 1 cubic yard = 10^6 cubic cm. The original definition of the gram was the weight of one cc of water. As Google calculator will happily tell you, "one metric ton per cubic meter in pounds per cubic foot" is 62.4279606. Up to the minor variation in density due to temperature, this is the actual weight of a cubic foot of water -- the 64 lbs, ie "a pint's a pound," is a fine approximation, but not exact. And one metric ton = 2204.62262 pounds. --Michael -- It is very dark and after 2000. If you continue you are likely to be eaten by a bleen.
