You'd have to be more specific. Are you talking about Class 1 or Class 2 rip rap, 67M, 78M, #5, etc, etc, etc? Different sizes cut of stone are going to have different weights per cubic yard.
there is about 1.25 yards to a ton,so 22.5 tons would be approx 18 yards
There is about 2800lbs in 2 yards of top soil.
5 cubic feet
Something on the order of .6 yards per US ton
The answer depends on how deep the coverage will be. River Rock weighs 2,800 LBS. per cubic yard - That's 1.4 tons per cubic yard. One ton = 2,000 LBS. 2,000 divided by 2,800 equals roughly 0.71. So one ton of river rock is roughly 0.71 cubic yards. 0.71 cubic yards covers roughly 230 square feet 1" deep 0.71 cubic yards covers roughly 115 square feet 2" deep 0.71 cubic yards covers roughly 77 square feet 3" deep 0.71 cubic yards covers roughly 57 square feet 4" deep 0.71 cubic yards covers roughly 38 square feet 5" deep
1,000 lbs or 454 Kilograms
There are approximately 1.2 cubic yards in a ton of item 4, but this can vary slightly depending on the density of the material and how tightly it is packed.

The conversion rate between cubic yards and tons varies depending on the material being measured. For example, one ton of gravel typically equates to about 0.55 cubic yards, whereas one ton of topsoil is roughly equivalent to 0.75 cubic yards. It's important to check specific conversion rates for the material in question.
The rule of thumb for wood chips is that they weighs 550 pounds per cubic yard. So a ton of wood chips would equal about four cubic yards.
A university extension website would tend to be an authoritative, respected source of information. The Sanpete Cooperative Extension in Ephraim, Utah, links 60,000 cubic yards of turkey litter with 24,700 tons. That would be about 2.43 [2.429121] yards.
It depends what kind of waste it is. A cubic yard of soil is aprox. 1 ton.
