  • The Density of Common Rocks and Minerals

    The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water. This isn't as complex as you may think because water's density is 1 gram per cubic centimeter or 1 g/cm 3. Therefore, these numbers translate directly to g/cm 3, or tonnes per cubic meter (t/m 3).

  • How Much Does a Yard of River Rock Weigh?

    A yard of river rock weighs 2,700 pounds and is equivalent to 1.35 tons, according to Cedar River Garden Center. A typical skid loader delivers a yard of river rock in two scoops. The yardage is calculated by multiplying the length by the width in feet times the desired depth in inches. The product is divided by 324 to determine cubic yards.
