Convert from quintal [metric] to hundredweight [short, US]

Unit Definition (quintal [metric])
The quintal [metric] is a common metric unit of mass equal to 100 kilograms or approximately 220.4623 pounds. Notice that the metric ton is roughly equal to its non-metric predecessors, but the metric quintal is about twice the size of the traditional quintal.

Unit Definition (hundredweight [short, US])
The hundredweight is a traditional unit of weight equal to 1/20 ton. In the United States, where the currency was decimalized and there wasn't so much need to align the unit with the quintal and zentner, the hundredweight came to equal exactly 100 pounds (about 45.3592 kilograms). The U.S. hundredweight seems to have been invented by merchants around 1840. 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.
