Information About

Hundredweight




  • In Imperial Units , a hundredweight ('long') is defined as 112 Pound s Avoirdupois , or 8 Stone , or four Quarter s. This is so close to 50 kg that the transition to metric equivalents has been easy. It has now been legally defined in Britain as 50.80234544 kg.

  • In U.S. Customary Units , a hundredweight ('short') is defined as 100 pounds. The short hundredweight is also the normal hundredweight in Canada .

  • ---The short hundredweight is also called a cental (which never means a long hundredweight), especially in places which normally use the long hundredweight. See Conversion Of Units


In both systems, there are twenty hundredweights to a Ton – the '' Long Ton '' of 2240 pounds (approximately equal to a Metric Tonne ), and the '' Short Ton '' of 2000 pounds. In both systems, the hundredweight is Abbreviated cwt, where ''wt'' is an abbreviation for Weight and ''c'' is an abbreviation for One Hundred (since the Roman Numeral C is equal to 100).

Prior to the 15th century in England, a hundredweight used the old hundred of 108 lb, giving a ton of 2160 pounds. In some industries (notably forges) this old hundred was retained somewhat longer. The London hundredweight of 112 pounds eventually replaced the old hundred.

The short hundredweight is commonly used in the sale of Livestock and some Cereal grains and Oilseed s and on Futures Exchange s. The long hundredweight is now little used in any country, except sometimes for measuring the Bells used for Change Ringing . In the UK and Ireland, the few household commodities that were commonly sold by the hundredweight, such as Coal and some Building Material s, are now sold in 50 kg quantities. For most purposes metric units are now in use in the UK, while other Commonwealth countries and Ireland have adopted the metric system in full.
