What is the volume in cubic yards of 27 metric tons of gravel?

Answer 1

As there are several "types" of gravel, we may have to "average out" the densities. Or we could make some calculations for some different "flavors" of gravel. Dry, loose gravel weighs a bit over 1522 kg/m3 - 23.24 cu yd/27 tonnes Gravel with sand weighs a bit over 1922 kg/m3 - 18.40 cu yd/27 tonnes Dry gravel, 1/4 to 2 inch weighs about 1682 kg/m3 - 21.03 cu yd/27 tonnes Wet gravel, 1/4 to 2 inch weighs about 2002 kg/m3 - 17.67 cu yd/27 tonnes There are about 1.31 cubic yards in a cubic meter, and there are 1,000 kg in a tonne. Those are your conversion factors. As you depart from these gravel types, your volume of material will vary, naturally. Recall that aggregates are generally sold by volume, specifically the cubic yard, and weights are "not important" in the transaction. Your aggregate supplier will have figures for the density of his materials that should be pretty accurate.
