To find the tonnage you need know the density of the crushed stone you are using. I went to a web site in the UK that has densities of dry materials and it gave me the density of crushed stone as 1602 Kilograms per cubic metre. The density of your millings may be different, I have no way of knowing. I then used an online converter to convert this to pounds per cubic feet. This converter gave me
You have 98 cubic feet so the weight is 98 100 = 8900 pounds. This is them 9800/2000 = 4.9 tons.
