One or two grams in Hong Kong is about 37.5 grams. The mainland's "two" is 50g, one kilogram is equal to 1 2oz, and1kg is equal to 2oz, which is the traditional unit of measurement in China. However, in Hong Kong, the concept of "gold" is different. The port is 600g, which is equal to 16 Liang, and one Liang is equal to 10 yuan. So one or two grams in Hong Kong is about 37.5 grams.

The port adopts "Sima Jin" system, 16 beam. Sima Liang is a commonly used unit of measurement in Hong Kong's gold market at present, and Hong Kong gold is 1 two (Sima Liang) = 37.4438+0g.

Whether it is a jewelry store or a gold store in Hong Kong, the marked HKD 15000 is not the concept of "dividing by 50", but the HKD is first converted into RMB and then divided by 37.5g ..

For example, the exchange rate between Hong Kong dollar and RMB is 0.8 1 17, and a thousand gold necklace in a gold shop in Hong Kong is marked with 0.875 taels, and the price is HK$ 0.7800 per tael. Then the actual price is17800× 0.817 ÷ 37.5 = 385 yuan per gram (excluding commission and jewelry fee), and the total price is 0.875×17800× 0.81.

To buy gold abroad or abroad, we must understand the overseas pricing mechanism, understand the gold content, and use a calculator to convert the exchange rate, so as to buy back real gold and silver with reasonable cost performance.
