The hundredweight (abbreviation: cwt), formerly also known as the centum weight or quintal, is a British imperial and United States customary unit of weight or mass. Its value differs between the United States customary and British imperial systems. The two values are distinguished in American English as the short and long hundredweight and in British English as the cental and imperial hundredweight.
- The short hundredweight or cental of 100 pounds (45.36 kg) is defined in the United States customary system.[1]
- The long or imperial hundredweight of 8 stone or 112 pounds (50.80 kg) is defined in the British imperial system.[2]
Under both conventions, there are 20 hundredweight in a ton, producing a "short ton" of 2,000 pounds (907.2 kg) and a "long ton" of 2,240 pounds (1,016 kg).
