- ยง 'Amount is a counting quantity, converting the counting unit [x] into moles [mol] using the Avogadro constant, NA.
- $ '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.
- โฌ 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.
