This standard adopts the international standard ISO 02955-18B8 (H) "Information processing - Representation of international units and other unit codes for use in limited character systems".
When applying this standard to assemble unit codes, the relevant provisions and application principles in GB 31008 "International unit systems and their application" should be followed.
1 Main content and scope of use
This standard specifies the composition of the International System of Units (SI) code, the structure of SI prefix codes, SI unit multiple codes and the combination principles of SI unit codes. This standard also specifies other legal unit codes of my country that can be used in conjunction with the International System of Units. This standard is applicable to information exchange between information processing systems and related equipment. 2 Referenced standards

International system of units (S1) code is composed of two types: code and sub-code. 1 The digital code of the national standard unit system (S) [the digital code of the international standard unit system (S1) consists of four digits The Arabic numerals are shown in Figure 1. From the left, the first and second digits are the SI prefix code, and the third and fourth digits are the SI unit serial number. Since only the mass unit (kilogram) of SI units has a prefix, the others do not have a prefix. Therefore, except for the mathematical code of the mass unit (kilogram), the first and second digits of the other SI unit codes are set to "plus". Figure 1: The digital code structure of the International System of Units (SI) digital code Example 1: The digital code for the unit meter is GB, approved by the National Bureau of Standards on October 1, 1988 and implemented on February 1, 1988. 9548--88
Example 2: The length single value meter flash 1 into multiple units "meter effective code is 0301. .22 International single system (S [》) mother code of the nano system (S) mother code quantity refers to the British International Standard 1S02955-1983 (E), there are two formats: suitable for those who use both human letters and letters (m), numbers and other graphic symbols. These graphic symbols include at least micro (), 5 (), to Ning Jian (一), dot or interval . and line (/). This type of system is mostly used for the characters, numbers and symbols of the upper blood association. 2:15 61 is an example of this type of character filing format II, which is suitable for only one type of character (people or small characters, numbers and other shapes. These shadows are connected by brackets (a), dots or the first two diameters (, slant (). This type of system is not used for the characters, numbers and other shapes, and the first two diameters (). and the ability to learn and study. : The case is of this type. The main purpose of the period is to avoid the exchange of information between data processing systems and related equipment and in the information transmission system, but it is not suitable for typing for comparison, nor is it suitable for other forms of communication and communication. In the case of mail, the format 1 and the format knife are the same as the drum 1S0 quantity 1501000 = purchase symbol. If 1S031 or 101 cannot be used, the unit name of the period can be used.

According to the provisions of Article 4.4.12 of the "Plan for the Use of Legal Units", the use of 100 million (100 million) and 10,000 (10) is not restricted. They can be used to form multiple units, but they are not header codes. Because the two numerals 100 million (100 million) and 10,000 (100 million) are widely used, these two numerals are specially coded: they can form a borrowed unit code with the unit code, but they are not header codes and should not be combined with header codes. The codes for these two numerals are shown in Table 5 Table 5 Numeral Codes

7.1$I unit 1 reverse multiple single to single number code, is to replace the first digit "ou" of table 1, table 2. Table 3 5I single number code with the SI buy number 2 code, the first and fourth digits remain unchanged, thus forming the 5I unit multiple unit code
for example; the number code is 0301.T.The decimal code of the SI unit is to reverse the letter code of S1 in Table 4, replace 1 with 2 and the letter code of the S unit on the left, so that the SI unit code of the multiple is formed. For example, the code of meter km.
: The name of the unit is "gram", which is called the head "", so the decimal code of the product is the product. It is to put the intermediate number code and the "2" before the "product", and the decimal code of the product is the product of the product. The code is:
B combined unit code
B.! The combined unit code is formed by the SI unit through the combination of the SI unit code and the combination number. For example: the digital code of the meter is 0021,0001, and its mother code is N·m. .2 The code of the combined unit formed by dividing the SI units is represented by the combination code "S". Example: The digital code of the unit of internal energy per joule (mol) is 0024/06, and its code is "/l". 8.3 The code of the multiple of the combined unit shall be in accordance with (310, 1502955-1983 (E) Information Processing - International System of Units and Other Unit Systems for Use with Limited Character Sets and the relevant provisions of this standard Monthly combination method. Example 1, the multiple of a unit is represented by the number 0322000: (], its digital code is k·. 9 Unit code representation with exponents (including positive exponents and negative exponents), 1 The mathematical representation of a unit with an exponent (including positive exponents and negative exponents) is to add a small bracket () after the unit number, and enclose the exponent (positive or negative exponent) in the brackets. Example 1, the digital representation of meter is (?)
