Convert from jupiter to tahil [China]

Unit Definition (jupiter)
The jupiter is a unit of mass, now being used in astronomy to express the masses of new planets being discovered in orbit around various stars. It's equal to the mass of the planet Jupiter, estimated to be about 1.899 x 10E24 metric tons, or, if you please, 1.899 yottatonnes (Yt). By coincidence, this is approximately 0.001 Sun (0.000 955 Sun, to be more exact).

Unit Definition (tahil [China])
The tahil is a traditional unit of weight used throughout eastern Asia. During the colonial period, the tahil was more or less standardized throughout the region at 4/3 ounce avoirdupois (1/16 catty, 1/12 pound, or about 37.8 grams). In Japan, however, the tahil was identified with a slightly smaller traditional unit and is considered equal to 1.323 ounces (37.51 grams). The tahil is usually considered equal to the Chinese liang.
