Frequently Asked Questions
Measure the length and width of the area in feet, and the desired depth in inches. The calculator multiplies these to get volume, then multiplies by the density to get weight, and converts to tons.
Common densities: Crushed stone ~100 lbs/ft³, Limestone ~110 lbs/ft³, Granite ~120 lbs/ft³, Sandstone ~95 lbs/ft³. Use the dropdown to select the appropriate material.
Using the calculator: Volume = 10x10x(4/12) = 33.33 ft³. With density 100 lbs/ft³, weight = 3333.33 lbs, tons ≈ 1.667 tons.
