The tael (Chinese: 兩; Pinyin: Liǎng), was part of the Chinese system of weights and currency. There were many different weights of tael depending on the region or type of trade. In general the silver tael weighed around 40g. The most common government measure was the Kuping (treasury) tael, weighing 1.2 Troy ounces (37.3g). A common commercial weight, the Tsaoping tael weighed 1.18 Troy ounces (36.7g) of marginally less pure silver.
