Canadian units
From Wikipedia, the free encyclopedia
Canadian units are the traditional weights and measures used in Canada. The country has officially adopted the metric system, but still maintains legal definitions of the imperial units under Schedule II, Section 4 of the Weights and Measures Act ( R.S., 1985, c. W-6 ).[1] Products sold in Canada may be labelled with any system of non-metric measurements in addition to metric values provided that the metric units are displayed more prominently than any other equivalent units of measurement.[2][3]
While these units are legally called "Canadian units", they are commonly called imperial units by many Canadians and taught as such in much of Canada.[4][5][6][7][8][9] The majority of these units are identical to the imperial units used in the United Kingdom, with the most visible exception being the use of the short hundredweight and ton as in the United States. Each unit has an official English and French designation. The following are the Canadian units of measurement as set out in the Weights and Measures Act.
