Counting units are, ten hundred, thousand, ten thousand, one hundred thousand, one million, ten million, one billion, ten billion, one hundred billion, one trillion, ten trillion, one hundred trillion, gigabit, Beijing, ten Beijing, one hundred Beijing, one thousand Beijing, one hundred Taiwan Province, one hundred Taiwan Province and one thousand Taiwan Province. Ganges sand, 10 Ganges sand, 100 Ganges sand, 1000 Ganges sand, a monk rice, 10 a monk rice, 100 a monk rice, that's up to him.

Counting units shall include integer parts and decimal parts, arranged in the following order: 100 billion, 100 billion,100 billion,100 million,100 million, one tenth, and one hundred. When writing numbers, if there is a decimal part, use the decimal point (. ) to separate integers from decimals.

(1) Lesson 12 of Esperanto Textbook published by China Press, "How much is one trillion?" It is clearly stated that one trillion is milion-oble miliono=biliono (one million millions, that is, the power of 10/2). To count these trillions, if calculated at 200 per minute, that is 12000 per hour, 288000 per day, and105120000 per year (105120000). It will take more than 9500 years to count one trillion. It will take generations! This trillion is 1 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.

(2) However, the "trillion" referred to by modern science and technology is by no means "trillion", but "million", that is, million (that is, the sixth power of 10). It is one millionth of a trillion, in other words, the difference between 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!

(3) The counting unit of time is the one we are most familiar with. The counting units of milliseconds, seconds, minutes, hours, days and years are different: 1 second = 1000 milliseconds 1 minute =60 seconds 1 hour =60 minutes 1 day =24 hours and 64 hours.

(4) Number of counting units of stamps: it is the smallest unit of measurement of stamps, and refers to stamps with independent functions.

Number of sheets: the counting unit of all sheets (including souvenir sheets, sheetlets, sheetlets, etc.). ). Print the whole paper: refers to the paper printed from the printing machine. Post office stamp: the whole stamp printed by the stamp printing factory in the form of finished products is packaged and sent to the post office for sale, which is called post office stamp.
