In North America, it was used in colonial French establishments in early New France, French Louisiana (La Louisiane), and Quebec. The Portuguese toise (in Portuguese: toesa) was used in Portugal, Brazil and other parts of the Portuguese Empire until the adoption of the Metric system.In geometric measurements, length most commonly refers to the longest dimension of an object. In certain contexts, the term "length" is reserved for a certain dimension of an object along which the length is measured. For example it is possible to cut a length of a wire which is shorter than wire thickness. Another example is FET transistors, in which the channel width may be larger than channel length.
