Since numbers become cumbersome and confusing long in very large or very small scales, it is a good idea to do not write the numbers in their full length and to write an abbreviation instead. Prefixes for the powers of ten are grouped into sets of three zeros, with smaller increments near the number 1. If youre ready to move on, check out this helpful list of the abbreviations for basic metric system units. However various other abbreviations remained common, including "mic", "mm", and "u", in part motivated by the lack of a "" key on most typewriters.

[citation needed], Larger volumes are usually denoted in kilolitres, megalitres or gigalitres, or else in cubic metres (1 cubic metre = 1 kilolitre) or cubic kilometres (1 cubic kilometre = 1 teralitre). Because the SI prefixes strictly represent powers of 10, they should not be used to represent powers of 2. The reason is that this particular skill isn't really mentioned by chemistry (or physics) teachers. Spelling out scientific notation numbers can be a mouthful. This prefixes are also called SI-prefixes, where "SI" is an abbreviation for the French term "Systme international d'units" (International System of Units).
