  1. Kilo-

    kilo is a unit prefix in the metric system denoting multiplication by one thousand. It has been used in the International System of Units where it has the unit symbol k, in lower case. The prefix kilo is derived from the Greek word χίλιοι, meaning "thousand". It was originally adopted by Antoine Lavoisier's research group in 1795, and introduced into the metric system in France with its establishment in 1799. Examples: ⁕one kilogram is 1000 grams ⁕one kilometer is 1000 metres ⁕one kilojoule is 1000 joules ⁕one kilobaud is 1000 bauds ⁕one kilobit is 1000 bits ⁕one kilobyte is 1000 bytes. A second definition has been in common use in some fields of computer science and information technology, which is, however, inconsistent with the SI. It uses kilo as meaning 210 = 1024, because of the mathematical coincidence that 210 is approximately 10³. The NIST comments on this confusion: "Faced with this reality, the IEEE Standards Board decided that IEEE standards will use the conventional, internationally adopted, definitions of the SI prefixes." ⁕one kilohertz is 1000 hertz
