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 Ml2T-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.
Note that the seven base dimensions are M (Mass), L (Length), T (Time), Q (Temperature), N (Aamount of Substance), I (Electric Current), and J (Luminous Intensity).
