**Quad**

**Quad (quad)**is a unit in the category of

*Energy*. It is also known as quads. This unit is commonly used in the US unit system. Quad (quad) has a dimension of Ml

^{2}T

^{-2}where M is mass, L is length, and T is time. It can be converted to the corresponding standard SI unit J by multiplying its value by a factor of 1.05505585262E+018.
