Glossary » Units » Electric Charge Density » A.u. of Charge Density
A.u. of Charge Density (a.u.) is a unit in the category of Electric charge density. It is also known as atomic units, u.a., au, ua. This unit is commonly used in the a.u. unit system. A.u. of Charge Density (a.u.) has a dimension of L-3TI where L is length, T is time, and I is electric current. It can be converted to the corresponding standard SI unit C/m3 by multiplying its value by a factor of 1.081202621E+012.
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).

Other units in the category of Electric charge density include Coulomb Per Cubic Foot (C/ft3), Coulomb Per Cubic Inch (C/in3), Coulomb Per Cubic Meter (C/m3), Coulomb Per Cubic Micron (C/µm3), and Coulomb Per Cubic Millimeter (C/mm3).
