In English-speaking countries, a unit of mass = 100 pounds avoirdupois, about 45.359237 kilograms. Symbol, ctl.

In Britain (where a hundredweight = 112 pounds), the term was first suggested in the Report of 1841 by the commission studying how to proceed after the fire that destroyed the United Kingdom’s prototypes. By 1859 the cental was in use for grain. An Order in Council on 4 February 1879 legalized it, persuant to section 8 of the 1878 Weights and Measures Act. The half-cental was legalized on 9 October 1903.

With many other units, it had to be abandoned when the United Kingdom became part of the European Economic Community (Statutory Instrument No. 484, 1978).
