**A cubic foot of soil weighs between 74 and 110 pounds, depending on the type of soil and how moist it is.** Dry, loose dirt weighs about 76 pounds per cubic foot, while moist, loose dirt weighs 78 pounds per cubic foot. A cubic foot of top soil weighs about 96 pounds, and a cubic foot of dry, screened top soil weighs 44 to 48 pounds.

A cubic foot of clay weighs approximately 100 pounds if dry and 110 pounds when moist.

Estimating the weight of soil is important when transporting it. A truckload of average dirt is about 18 cubic yards, or 486 cubic feet, which can be multiplied by the weight per cubic foot of the particular type of soil. A regular wheelbarrow carries 2 to 3 cubic feet of dirt, and a large wheelbarrow holds about 5 cubic feet of dirt. It would take approximately 194 trips with a regular wheelbarrow to empty a truckload of dirt.

A square foot of soil covers approximately 6 square feet if spread 2 inches deep, 4 square feet if spread 3 inches deep, 3 square feet if spread 4 inches deep, and 2 square feet if spread 6 inches deep.
