  • cubic yards to tons

    Hello,

    I need to convert cubic yards to tons. If I have 583 cubic yards of soil that is a silty sand (assuming the density of the silty sand is 0.7 g/cm3), how do I calculate how many tons this will be?

    Re: cubic yards to tons

    Hi, easiest to convert cubic yards to cubic meters first, as g/cm^3 is the same as kg/m^3.

    583cubic yards = 446m^3. The weight of 446 cubic meters of material of density 0.7 is 446 x 0.7 = 312 kg.

    0.7 would be a very low density for any type of sand. Water has a density of 1.0 at 25C, and only some of the very light metals, oils and organic solvents have densities lower than 1.0. The only other materials with low densities are things like natural or synthetic foams and fillers, which are made or formed with LOTS of air in the structure.

      gram/cubic centimeter is actually 1000 kilogram/cubic meter. (its the same as kilogram/liter)

      0.7 g/cm * 1000 = 700 kg/m

      446 m * 700 kg/m = 312,200 kg

      312,200 kilogram = 344.14 U.S. ton

        Yes, sorry, complete brain freeze. I meant metric tons, not kilograms. I still think 0.7 is too light a density for normal silt, though.

          [QUOTE=Unregistered]Hello,

          I need to convert cubic yards to tons. If I have 256 cubic yards of rock that my daughter needs to have delivered for her driveway but we need to know how many tons that will be can you help?

            That depends on the type of rock.

            Loose dry gravel weighs about 1.25 U.S. tons/cubic yard.

            256 cubic yards * 1.25 tons/cubic yard = 320 tons

            Other types of rock will differ though.

                Can you provide information on what crusher run is? I will have to try and look up the density.

                  How much is the loose dirt weighs per cubic yard? I don't know the details about the dirt but lets assume regular dirt. Please let me know.
                  Thanks.

                    dry excavated earth weighs about 78 pounds per cubic foot.

                    Thats about 2106 pounds per cubic yard.

                      For what its worth, we use an estimate of 2900 lbs per cubic yard of dry crusher run BUT 3250 lbs per cubic yard installed with 12% swell factor.

                      "We" being a construction company that deals with DOT projects that use quite a bit of crusher run.

                            If i had an invoice with say 50yards to washed sand. How can i work this out into tons? What is the formula used for this calculation?

                              Does septic sand run about 1.5 tons per cubic yard? Or was it 1.25 tons per cubic yard?
