Currency conversion in Han dynasty?

1 Basic Unit There were many monetary units in ancient China, which were different in each dynasty, especially before Qin and Han Dynasties. Only three basic units are discussed here: a piece of paper for making money (that is, a standard square hole copper coin), a silver and a gold. Although the units in the past dynasties are different, at least there is little difference after the Tang and Song Dynasties, so relatively stable and reliable data can be obtained. The exchange relationship between copper, silver and gold, just like the current foreign exchange price, is constantly changing, unlike 1 yuan equals 100 points. According to the following description: "The price of gold and silver rose from 1: 8 around 1600 to 1: 10 in the middle and late 20th century, and doubled to 1: 20 by the end of 18." It is known that 1 gold can be exchanged for about 8~ 1 1 silver. Then there is: "In the early years of Daoguang, one or two pieces of silver were exchanged for silver, that is, one thousand articles; By the time of the Opium War in the 20th year of Daoguang, one or two pieces of silver could be exchanged for sixteen thousand seven hundred pieces of silver. Since Xianfeng, the price of silver has soared, and one or two pieces of silver can be exchanged for as much as 22,300 pieces of silver. " It is known that under normal circumstances, 1 silver can be exchanged for about 1000~ 1500 copper. Ancient 1 penetration money or 1 hanging money was 1000 copper coins. 2 metal price because money made of gold, silver and copper is valuable in itself, and theoretically the value of money should be equal to the price of metal, so we can answer "how much is a silver?" In the Tang Dynasty, each Kaiyuan Bao Tong copper coin was 8 cents in diameter, 10 pieces weighed 1 2 pieces, and 1,000 pieces weighed 6 Jin 4 liang. During the reign of Shunzhi in the Qing Dynasty, each copper coin weighed one yuan and twenty-five cents, and then increased to one yuan and four cents, so it weighed eight catties and twelve ounces per thousand articles. In ancient times, although the weight units of "two" were different, they were all about 40 grams, while "Jin" was about 700 grams. The average weight of each copper coin is 5g. At present, the price of gold, silver and copper (RMB) is as follows: gold: 100 yuan/gram of silver: 2 yuan/gram of brass: 0.02 yuan/gram. The calculated result is: 1 two gold: about 4000 yuan 1 two silver: about 1 copper coin 80 yuan (/. Eight dollars and three cents for rice (stone)? White? According to the records of the Ministry of War of the Qing Dynasty, the grain prices of Shuntianfu, Daming and Xuanhua in Zhili in the first half of the 15th year of Guangxu were calculated on the basis of millet, sorghum and corn, with an average of 124 cents per warehouse. Calculated by 1 stone = 100 kg =70 kg, and calculated by 2 yuan RMB/kg, the following average values can be obtained: 1 two silver: about 170 yuan, 1 copper coin (1 paper coin). Now silver has been used as an industrial product, so the reference value of silver price is low. Due to the rapid development of agricultural technology, the relative price of grain is much cheaper than that in ancient times. 4. Respect the ancient exchange ratio, 5. Round the whole number up, which is easy to convert and establish perceptual knowledge. Therefore, the author suggests that the following conversion system should be adopted when encountering ancient monetary units in the future. Convenience and feeling: 1 two gold = RMB 2000 = 10 two silver 1 two silver = RMB 200 yuan = 1000 = 1 off (diao) money 1 = RMB 0.2 yuan in addition:/. 5 verification, the following provides some ancient materials to verify the conversion method given by Kobayashi, in order to improve the perceptual knowledge: the monthly salary of Jiupin officials in Tang Dynasty is 5 stone meters = the monthly salary of junior civil servants in Tang Dynasty 1000 yuan; The annual salary of six officials in the Qing Dynasty is 45 taels of silver = the annual salary of bureau-level cadres in the Qing Dynasty is 9000 yuan; Three years to clear the magistrate, 100 thousand snowflakes silver = those officials, that family is not tens of millions? In the early years of Qianlong, I donated a Taiwanese flower 13 122 silver = 2.7 million yuan to buy a departmental level cadre, which was clearly marked.
