I don't know. Maybe because tonnage can be converted to whatever unit of measure you want. By the way, did you factor in that a "tonne" is a metric ton, 1000kg or 2200 lbs?

Yes I did.

I did an "Ask Jeeves" for the weight of a gallon of coil, for which the answer is 6 to 8 pounds. (I selected 7 as a sensible average)

I multiplied 4300 x 2200 and then divided the product by 7 which resulted in over 1.35 million.

Usually the media likes to sensationalize things so it struck me a little odd that they reported the spill in tonnage when 1.3 million sounds much worse IMO.
