k 1. kilo (k). From Greek khilioi, meaning thousand. 2. In transmission systems, kHz (kiloHertz) is a thousand (103) Hertz, kbps (kilobit per second) is a thousand (103) bits per second, and km is a thousand (103) meters. In transmission systems, therefore, a thousand is exactly 1,000, since the measurement is based on a base 10, or decimal, number system. 3. In computing and storage systems, a kB (kiloByte) is actually 1,024 (210) bytes, since the measurement is based on a base 2, or binary, number system.The term kB comes from the fact that 1,024 is nominally, or approximately, 1,000. So, 64 kB of memory is actually 65,536 (216) bytes. 4. The only letter worth five points in the American version of Scrabble, the popular board game. |
