How big is a trillion? Add 20! !

In the twelfth lesson of the Esperanto textbook published by China News Agency, "How much is one trillion", it is clearly pointed out that one trillion is milion-oble miliono=biliono (one million, that is, 10 to the second power). To calculate this trillion, if we calculate 200 per minute, it is 12000 per hour, 288000 per day, and it is105120000 per year (105120000). It will take more than 9500 years to count one trillion yuan. How many generations will it take to count this trillion? It is more than 769 times of China's population of 65.438+300 million. However, we often encounter "omens" in our daily work. For example, there is an instrument frequency of megahertz, an instrument resistance of megaohms, a radio pressure of megapascals, and so on. However, the "trillion" referred to by modern science and technology is by no means "trillion", but "million", that is, 106. ) is one in a trillion, in other words, the difference between the two "trillions" is one million times. If you calculate according to the above method, you can calculate the last trillion in about three and a half days!

Who is right about this? In fact, they are all right. What's going on here? Because they originated from different counting systems in ancient China. In ancient China, there were three methods to calculate large numbers of more than 100 million: this method was found in Shu Shu Ji Yi in the Eastern Han Dynasty.

First, Buddhism is a self-multiplying system: one hundred million is one trillion, one hundred million is one trillion, and one trillion is Beijing. Archimedes of Greece also adopted this system; 10 4 = 10,000, 10 8 = 100 million,1kloc-0/6 = trillion, 10 32 = Beijing.

Second, China and France, which are both progressive systems, have made 10,000 advances: 1 trillion US dollars are in Beijing, and ditches (next to the earth) carry ┅ (10 trillion US dollars is trillion US dollars for Beijing ┅); 10 4 = 10,000, 10 8 = 100 million,10/2 = trillion,10/6 = Beijing.

Third, Xiafa is in decimal system, all in decimal system: the trillion trillion trillion trillion trillion trillion trillion system was popular in China until liberation, which was a trillion trillion trillion trillion trillion trillion trillion trillion ditch (next to the soil) carrying newspapers, all in decimal system. 10 4 = 10,000, 10 5 = 100 million, 10 6 = trillion, 10 7 = Beijing.

The "trillion" used in modern science and technology belongs to the third law, namely 10 6, that is, one million. Such as megacycles (MHz), megaohms (mω) and megawatts (MW); The modern "billion" belongs to the second kind, namely China and France (which is also consistent with the "billion" in the first law). 1300 million is equal to13 times the eighth power of 10 instead of the fifth power of 10.

Generally, in order to avoid confusion, "trillion" is only used in 10 6, and 10 12 means "trillion". No matter how big the number is, we should use "billions", "trillions", "billions", "billions" and "billions".
