^* For the quantities n, N and Q, the entities X have to be specified in the text or indicated by a subscript or in parentheses: n_X; N_X; Q_X.

^§ 'Amount is a counting quantity, converting the counting unit [x] into moles [mol] using the Avogadro constant, N_A.

^$ 'Count' is synonymous with 'number of entities'; the name, symbol and unit are not included in the SI as a base quantity or base unit.

^€ Charge is a derived SI quantity, included here for comparison. Charge is a counting quantity, converting the counting unit [x] into coulombs [C] using the elementary charge, e, or converting moles [mol] into coulombs [C] using the Faraday constant, F.
