A toise (; symbol: T) is a unit of measure for length, area and volume originating in pre-revolutionary France. In North America, it was used in colonial French establishments in early New France, French Louisiana (Louisiane), and Quebec. The related toesa was used in Portugal, Brazil and other parts of the Portuguese Empire until the adoption of the Metric system.
