#394: Kilobyte

There’s been a lot of confusion over 1024 vs 1000,

kbyte vs kbit, and the capitalization for each.

Here, at last, is a single, definitive standard:

[[table of various kinds of kilobytes]]

SYMBOL | NAME | SIZE | NOTES

kB | Kilobyte | 1024 bytes OR 1000 bytes | 1000 bytes during leap years, 1024 otherwise

KB | Kelly-Bootle standard unit | 1012 bytes | compromise between 1000 and 1024 bytes

KiB | Imaginary kilobyte | 1024 sqrt(-1) bytes | used in quantum computing

kb | Intel kilobyte | 1023.937528 bytes | calculated on Pentium F.P.U.

Kb | Drivemaker’s kilobyte | currently 908 bytes | shrinks by 4 bytes each year for marketing reasons

KBa | Baker’s kilobyte | 1152 bytes | 9 bits to the byte since you’re such a good customer
