Mike,

While your measure for a long ton was correct, the rest of the statement above
was a bit off. In the same paragraph you were mixing the measurment of volume
(i.e., gross tons and net tons), and measurements of weights (i.e., long tons
and short tons). This is akin to mixing apples and oranges!   :-)

2,240 pounds is not the weight of 100 cubic feet of sea water at all. Since sea
water is 64.1 lbs/cubic foot, 100 cubic feet of sea water would weight 6,410
lbs, not the 2,240 lbs. that you had thought.
