N.B.1. "Week", "month", and "year" (the symbol for "year" is "a") are units of time in common use.2. The word in the bracket[] can be omitted when the omission is not liable to cause confusion.3. The word in the parenthesis ( ) are synonyms for the words immediately before them.4. The symbols for angle units (degree, miniute and second) are put into parentheses when they are not preceded by numerals.5. In the symbol for the litre, the small letter "l" is an alternate synbol.6. "r" is the symbol for "revolving".7. "Mass" is commonly called "weight" in people's daily life and trade.8. "Gong li" is a popular name for "kilometre" and its symbol is "km".9. 10 exp 4, 10 exp 8 and 10 exp 12 are respectively called "wan", "yi", and "wan yi" in Chinese. The use of such numerals is not affected by the special terms listed in Table 5, but they should not be mixed up with the special terms.
