A yard of dirt is more commonly referred to as a cubic yard of dirt.
What is a cubic yard?
A cubic yard is a unit of volume or material that can fit inside a cube which is 3-foot long x 3-foot wide x 3-foot high.
So, how much does a cubic yard of dirt weigh?
If the dirt is dry, it can weigh approximately 2,000 pounds (907 kg).
A cubic yard of wet dirt can weigh around 3,000 pounds (1360 kg).
To know whether your soil is wet or dry, it is simply a matter of putting your hand in the soil and feeling for moisture.
If you are planning to buy the dirt for a project, it is always recommended to buy on a day which is dry. This makes it a lot easier to transport, not to mention work with.
One final note… if the dirt only consists of topsoil it will weigh around 1,080 pounds (489 kg).
