Passage: Ngoen  (เงิน) is Thai for "silver" as well as the  general term for money, reflecting the fact that the baht (or tical) is foremost a unit of weight for precious metals and gemstones. One baht = 15.244 grams. Since the standard purity of Thai gold is 96.5 percent, the actual gold content of one baht by weight is 15.244 × 0.965 = 14.71046 grams; equivalent to about 0.473 troy ounces. 15.244 grams is used for  bullion; in the case of jewellery, one baht should be more than 15.16 grams.
