On the one hand, this abbreviation can be made by specifying the powers that are also listed in the table (for example 3.28*10^24 meters) and on the other hand, it can be made by using these SI-prefixes (for example 3.28 yottameters). Webster's New World 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. The metric system loves the prefix centi-, or one-hundredth. For example, a centimeter is one-hundredth of a meter, a centiliter one- hundredth of a liter, and a centigram? Below is a table of the most commonly used metric prefixes that can be added to the basic units of measurement. Metric system prefixes provide a simple way to understand exactly what each unit of measurement stands for in the metric system, since the prefixes tell you how much bigger a unit is than the base unit. Since 1960, the prefix is part of the International System of Units (SI). 100th of a liter = Centiliter Some other prifixes in metric: Milli = 1000th of say meter/liter etc.. Kilo = 1000 times a meter/liter etc. For instance, the NIST advises that 'to avoid confusion, prefix symbols (and prefix names) are not used with the time-related unit symbols (names) min (minute), h (hour), d (day); nor with the angle-related symbols (names) (degree), (minute), and (second),[15] whereas the BIPM adds information about the use of prefixes with the symbol as for arcsecond when they state: "However astronomers use milliarcsecond, which they denote mas, and microarcsecond, as, which they use as units for measuring very small angles."[18]. use in information technology.
