A ton is a measure of mass. A cubic foot is a measure of volume. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.
If you are not convinced, consider 40 cubic feet of air. How many tons? Next consider 40 cubic feet of lead. How many tons?
A 100 cubic feet of what? The mass of a 100 cubic feet of air would be substantially different from the same volume of lead, for example.
tons use of weight and cubic feet for the volume of the two compared with Rob Gelphman.
At 100 pounds per cubic foot, that is 20 cubic feet per ton = 0.57 cubic meters
Knowing that 1 cubic foot is pretty much equal to 100 pounds or 0.05 ton, 1 ton of gravel is around 20 cubic feet.
about 6 cubic feet
13.33 cubic feet
It varies with the soil. A cubic ft of compacted dirt weighs 100-120 lbs. Somewhere between 17 and 20 cubic ft to a ton. A cubic yard is about a ton and a half.

5 cubic feet
About 50
2.13 ton of what? Ton is a unit of mass, and cubic feet is volume. So you would need to know the density of the material, in order to determine volume from mass.
1 cubic metre = 1000 litres
sand weighs 100 pounds per cubic feet 2000 pounds is one ton 2000/100 = 20 cubic feet 1 meter = 3.28 feet 1 cu meter = 3.28 x 3.28 x 3.28 = 35.31 cu ft 20 cubic feet = 20/35.31 = 0.566 cubic meters
Sand is usually sold by the ton so if you find the amount needed by 100 x 1/6 this will give you your cubic foot total. Then you will divide by 27 which is the number of cubic feet in a cubic yard. You should have 16 cubic feet at these measurements. 16 divided by 27 is .59 or a little over half a cubic yard. There are 22 cubic feet of sand per ton so 1 ton of sand should do it. So if the sand in your area is sold by the ton then get 1 ton. If it sold by the yard get 3/4 yard if you can. Hope this helps.
