A netizen came up with a preliminary answer based on relevant information. However, this is just a rough estimate, just to give everyone a perceptual understanding.

Basic units and exchange relations

There were many monetary units in ancient my country, and they were different from dynasty to dynasty. Among them, one penny (i.e. a standard copper coin with a square hole), one tael of silver, and one tael of gold. Although these three units are different in each dynasty, they are not much different after the Tang and Song Dynasties.

The exchange ratio between copper coins, silver and gold, like the current foreign exchange prices, often changes. According to relevant information: 1 tael of gold can be exchanged for about 8 to 11 taels of silver; 1 tael of silver can be exchanged for about 1,000 to 1,500 copper coins. In ancient times, 1 guanqian or 1 hanging coin was usually said to be 1,000 copper coins.

Prices of precious metals

Although the weight unit of "liang" in ancient times was different, it was roughly equivalent to about 40 grams, while "jin" was about 700 grams. Each copper coin The average weight is 5 grams.

The current price (RMB) of gold, silver and copper is approximately: gold 100 yuan/gram, silver 2 yuan/gram, and brass 0.02 yuan/gram. It can be calculated from this: 1 tael of gold is worth about 4,000 yuan, 1 tael of silver is worth about 80 yuan, and 1 copper coin (1 Wen coin) is worth about 0.1 yuan.

Grain prices

Many historical monographs use grain prices to directly measure currency relationships. Although grain prices alone are not very accurate and objective, they should be an extremely important reference. Relevant data show: "According to the records of the Military Aircraft Department of the Qing Dynasty, the grain prices in Shuntian Prefecture, Daming Prefecture, and Xuanhua Prefecture in Zhili Province in the first half of the fifteenth year of Guangxu's reign were calculated based on the three types of grains: millet, sorghum, and corn. The average price was one silver per stone. "Two four cents and six cents"

If the grain price is calculated at 2 yuan (RMB) per kilogram, the following average value can be obtained: 1 tael of silver is worth about 170 yuan, and 1 copper coin (1 Wen currency). Approximately worth 0.2 yuan.

How much is one tael of silver?

Based on the above calculation, consider:

1. The price of gold is more stable than others, so you should focus on it.

2. Silver is now regarded as an industrial product, so the current silver price reference value is low.

3. Due to the relatively rapid development of agricultural technology, the relative price of food now is much cheaper than in ancient times.

4. Respect the ancient exchange ratio.

5. Round up the numbers to facilitate conversion and establish perceptual understanding.

Therefore, when encountering ancient monetary units in the future, the following conversion system is convenient and intuitive:

1 tael of gold = RMB 2,000 = 10 taels of silver

1 Wenqian = RMB 0.2 yuan In addition: 1 stone = 1 tael of silver
