Some prefixes are also used in digital communications and computer technology but they have a slightly different value because they are based on a power of 2. In this problem, we started with $1.93\,×\,{10}^{13}\text{kg,}$ so we have 13 + 3 = 16 powers of 10. Metric prefixes are easy to understand and very handy for metric conversions. So there is no prefix for 10^-4 or 10… The number 200 can be expressed in scientific notation as 2 x 10 3. b. Units of various sizes are commonly formed by the use of such prefixes.The prefixes of the metric system, such as kilo and milli, represent multiplication by powers of ten. The top is the complete list of metric prefixes, symbols, and their powers. There is no such prefix. Using this table along with the metric system chart will result in a better understanding of the metric system. On the extremely large end of the spectrum, Peta (P) = 10 15, Exa (E) = 10 18, Zetta (Z) = 10 21, and Yotta (Y) = 10 24.

The above mentioned introduction really explains it quite nicely. We show these scale changes by using metric prefixes. For example, 103 = kilo, 106 = mega, 10-3 = milli, etc. 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. 6789 Quail Hill Pkwy, Suite 211 Irvine CA 92603. For example, meters, centimeters, and millimeters are all metric units of length. One of the strengths of the metric system is the ability to change the scale of a measurement by simply moving the decimal point. c.
