The capacity in tons of dry material depends on the density of the material, the number of pounds per cubic foot. For example I went to the SIMetric site in the UK and found the density of wheat to be 769 kilograms per cubic meter. I then used Google and typed 769 kilograms per cubic meter to pounds per cubic foot into Google's search window and got the reply (769 kilograms) per (cubic meter) = 48.0071017 pounds per (cubic foot). Thus your silo would hold 3,393 × 48 = 162,860 pounds of wheat which is 162,860/2,000 = 81.4 tons. Penny
