CU stands for "Cubic Unit," a measurement used to quantify volume in three-dimensional space. It is commonly used in various fields, including science, engineering, and architecture, to describe the capacity of objects or spaces. The cubic unit can be expressed in different metric or imperial systems, such as cubic meters or cubic feet. In addition to its use in volume measurement, CU can also refer to Colorado University, a public research university located in Boulder, Colorado.
