Cubic Yards
A cubic yard is an imperial volume unit equivalent to the volume of a cube with sides that are one yard in length. It is normally found in the United States for measuring large volumes of materials such as soil, gravel, or concrete.
When converting volume measurements, be sure to remember that the dimensions are cubed and so doubling the sides of a cube will increase the volume by a factor of eight.

Cubic Millimeters
Cubic millimeters are volume units in the metric system. A cubic millimeter is a unit of volume equal to the volume of a cube with sides measuring one millimeter each. It is a very small unit of volume commonly used to measure tiny amounts of liquids or solids. For example, a single drop of water may have a volume of approximately 50 cubic millimeters.
