Kibibyte (KiB)
A kibibyte is 1024 bytes (2¹⁰), the binary unit the IEC introduced so that “kilo” could keep meaning exactly 1000. Memory pages and file-system blocks are counted in KiB.
Symbol: KiB
Quantity: amount of digital information
SI relation: 1 KiB = 8192 bit (exact)
Derivation: 1 KiB = 2¹⁰ bytes = 1024 bytes.
Exact: yes, by definition
Typical uses
- RAM, cache and page sizes (4 KiB pages)
- File system block sizes
- Linux and programming tools
