QCalc.UsersGuide.Glossary.'quantity'

"property of a phenomenon, body, or substance, where the property has a magnitude that can be expressed as a number and a reference" [JCGM2012]

QCalc.UsersGuide.Glossary.'scalar unit'

a reference quantity that is used via multiplication to map a number to another quantity

QCalc.UsersGuide.Glossary.'specific'

adjective that indicates the quotient of the following quantity and its associated amount of substance [× N^-1]

Information

Note that that unlike the usual definition, "specific" does not indicate the quotient of a quantity and its associated mass; it is not synonymous with "massic." Also, since the quantities are written as if the Faraday constant is nondimensionalized (see Quantities), charge is an amount of substance and "specific" is equivalent to "per charge."
