PREFIXES for NUMBERS
Electronics, Radio and all of the Science fields use numbers that are wildly large and small. For the sake of working with these large numbers our culture has developed Prefix’s to keep the numbers small enough to be workable. These are the most useful Prefix’s with their abbreviations and the power of the number is listed.
