Convert from jin [China] to gigagram

Unit Definition (jin [China])
The jin is a traditional unit of weight in China, comparable to the English pound. During the European colonial era the jin was identified with the catty, a Malay unit widely used in various forms throughout East and Southeast Asia. Like the catty, the jin was then equal to 1 1/3 pounds or 604.79 grams. Traditionally, it was divided into 16 liang. In modern China, however, the jin is a metric unit equal to exactly 500 grams (1.1023 pounds) and divided into 10 liang. The kilogram itself is usually called the gongjin, or "metric jin." The spellings chin and gin also have been used for the jin.
