If the gold layer is 12 kt or higher, the minimum layer of karat gold in an item stamped gold-filled marks must equal at least 1 ⁄ 20th the total weight of the item. The most common stamps found on gold-filled jewelry are 1 ⁄ 20th 12kt GF and 1 ⁄ 20th 14kt GF.
A number of units of measurement were used in the Philippines to measure various quantities including mass, area, and capacity. The metric system has been compulsory in the country since 1860, during the late Spanish colonial period. [1]
The koku (斛) is a Chinese-based Japanese unit of volume. 1 koku is equivalent to 10 to or approximately 180 litres (40 imp gal; 48 US gal), [a] [1] or about 150 kilograms (330 lb) of rice. It converts, in turn, to 100 shō and 1000 gō . [ 2 ]
The catty is traditionally equivalent to around 1 + 1 ⁄ 3 pound avoirdupois, formalised as 604.78982 grams in Hong Kong, [1] 604.5 grams historically in Vietnam, [2] 604.79 grams in Malaysia [3] and 604.8 grams in Singapore. [4] In some countries, the weight has been rounded to 600 grams (Taiwan, [5] Japan, Korea [6] and Thailand).
