Convert from qintar [Arab] to libra [Italy]

Unit Definition (qintar [Arab])
The qintar is a traditional Arabic unit of weight, often called the cantar in English. The qintar is the Arabic counterpart of the European quintal. The unit varied in size from market to market and over time. In recent years, the qintar has been interpreted as an informal metric unit equal to 50 kilograms (110.23 pounds); traditional qintars tended to be a few percent larger than this. The qintar is equal to 100 rotls.

Unit Definition (libra [Italy])
The libra [Italy] is a traditional unit of weight. The libra was the Roman unit from which the English pound is descended; the symbol "lb" for the pound comes from this unit. The traditional Italian libbra was often of similar size, but a wide variety of libbras were used in Italian markets over the centuries. The word "libra" is sometimes used now for the kilogram, a much larger unit.
