I am trying to work out a price of steel pipe that I have. I have 900 metres of 9 5/8 inch pipe it weighs 40 pounds per foot and the price is $1,600 a metric ton.

Now if I want to get the price per metre then I understand that I have to divide by 2204.62, which is about how many pounds in a ton, then I multiply by pounds per foot, which is 40, then I then multiply by 3.281, which is about how many feet in a metre, and this gives me a price of $95.24 per metre which seems about right.

However what confuses me is that I have noticed that doing it the opposite way does not give me the original $1,600 price. For example to work out price per metre into price per metric ton I would multiply by 3.281 then multiply by 2204.62 and then divide by 40 (pounds per foot) This gives me an answer of 17,222 which is not the original $1,600. And so therefore I have concluded that I am doing something wrong somewhere in one of these, or both of these equations. I would appreciate any feedback that is given.
