Convert from hundredweight [long, UK] to metric ton

Unit Definition (hundredweight [long, UK])
The hundredweight [long, UK] (Cwt or cwt) is a traditional unit of weight equal to 1/20 ton. The hundredweight is the English version of a commercial unit used throughout Europe and known in other countries as the quintal or the zentner. In general, this unit is larger than 100 pounds avoirdupois, so to fit the European market the hundredweight was defined in England as 112 pounds avoirdupois (about 50.8023 kilograms) rather than 100 pounds. This definition apparently dates from about the middle of the 1300's. The British hundredweight was divided into 4 quarters of 28 pounds, 8 stone of 14 pounds, or 16 cloves of 7 pounds each. To distinguish the two hundredweight units, the British version is often called the long hundredweight and the American is called the short hundredweight or cental. The C in the symbol is of course the Roman numeral 100.

Unit Definition (metric ton)
The metric ton is a unit of mass used in mining to measure the mass of the valuable metal in an ore. Customarily, the metric ton unit is defined to be one metric ton of ore containing 1% metal, but it is the metal, not the ore, that is being measured. Thus the unit is really a unit of mass equal to 10 kilograms (22.0462 pounds).
