K

(1) Often used in place of “k” for one thousand, but precisely means 1,024 bytes, abbreviated KB.

(2) Temperature measured by the Kelvin scale. The various film and TV lighting sources are always measured by the Kelvin scale, and most color film stocks are balanced to give proper color reproduction at either 3,200→K (tungsten-halogen lamps) or 5,400→K (noonday sun).
