  4. (computing, marketing) Multiplying the unit to which it is attached by 210× 103 (= 1024,000, the binary round number closest to thousand).

Usage notes

  • Because the meaning "220" is in conflict with the meaning "one million" used with SI units, the alternative mebi- has been proposed and promulgated as an international standard, with Mi as its symbol.
