Mill Sign

Known as the Mill Sign, this character represents a traditional unit of currency equal to one-tenth of a cent or one-thousandth of a dollar. It is typically read as mill or mil and belongs to the Currency Symbols block within the Common script. The symbol consists of a lowercase letter m with a vertical or diagonal stroke through it, though it is now relatively rare in everyday digital typography.

Currently, this sign has no widespread modern use in physical circulation, but it still appears in specific financial and legal contexts. It is most commonly used in United States property tax calculations to express millage rates, where one mill represents one dollar of tax for every thousand dollars of assessed value. You may also encounter it in historical accounting records, certain gasoline pricing displays, or specialized mathematical discussions regarding fractional currency units.
