ML, when the unit of measurement is expressed by letters, the letters of unit symbols are generally lowercase; When the unit comes from the name, the first letter of the symbol must be capitalized. Only the unit of volume "L" is special, and this symbol can be written as capital L or lowercase L. This is because the symbol of "L" is lowercase at first, and it is difficult to distinguish lowercase L from Arabic numeral 1. Later, the International Metrology Congress made a resolution to write the symbol "L" as a capital L, so that lowercase L can be used with capitalized L, which is the only symbol in the international system of units that can be capitalized instead of named after scientists.
