In Spain, a unit used to measure the tonnage of ships, originally 8 cubic codos de ribera (about 1.53 cubic meters). As a result of an international conference on tonnage held in Constantinople on 2 December 1874, the tonelada de arqueo = 2.83 cubic meters (which is 100 cubic feet). An order of 27 January 1879 introduced the term tonelada métrica de arqueo = 1 cubic meter or 1000 liters. Finally, a regulation of 25 September 1900 reconfirmed the tonelada de arqueo = 2.83 cubic meters.
