单词 kilo-
释义
kilo-

Physics
  • Symbol k. A prefix used in the metric system to denote 1000 times. For example, 1000 volts=1 kilovolt (kV).


Chemistry
  • A prefix used in the metric system to denote 1000 times. For example, 1000 volts=1 kilovolt (kV).


Chemical Engineering
  • A prefix used in the metric system to denote a factor of 1,000.


Computer
  • A prefix indicating a multiple of 103 (1000), as in kilogram and kilowatt; the symbol for kilo- should then be k (not K), as in kg and kW. When the binary number system is used in a structure or process (as in semiconductor RAM or ROM), kilo- then indicates a multiple of 210 (1024), as in kilobyte and kilobit; the symbols k and K are both commonly used, as in kB or KB (symbols for kilobyte). The context usually clarifies which meaning of kilo- is intended, although being numerically close the meanings are often considered more or less equivalent. However, special care should be taken to disambiguate the intended meaning of this prefix when telecommunications and computing are both at issue. See also binary prefixes.


Electronics and Electrical Engineering
  • 1. (Symbol: k) A prefix to a unit, denoting a multiple of 103 (i.e. 1000) of that unit: one kilometre equals 103 metres.

    2. (Symbol: k or K) A prefix used in computing to denote a multiple of 210 (i.e. 1024). See kilobit; kilobyte.


Biology
  • Symbol k. A prefix used in the metric system to denote 1000 times. For example, 1000 volts=1 kilovolt (kV).
