An asterisk ( * ) indicates the default context, an at sign (@) indicates an abbreviation, and under the prefixes column, SI indicates that the unit takes all SI prefixes, IEC indicates that the unit takes IEC prefixes, and SI+ and SI- indicate that the unit takes only positive and negative SI prefixes, respectively. Refer to a unit in the Units package by indexing the name or symbol with the context, for example, permittivity[Atomic] or kappa0[Atomic]; or, if the context is indicated as the default, by using only the unit name or symbol, for example, permittivity or kappa0.

|
An atomic unit of permittivity is defined as farad per meter where c is the magnitude of the speed of light, and is energy-equivalent to the dimensionless unit 1.
