KiB to KB Converter
Convert kibibytes (KiB) to kilobytes (KB). 1 KiB = 1.024 KB.
How to convert KiB to KB
Kibibytes and kilobytes are both different kinds of units. One KiB is 1,024 bytes and one KB is 1,000 bytes, so multiply a KiB value by 1.024 to get KB.
Watch out: this conversion crosses between decimal and binary units. KiB is based on 1024 while KB is based on 1000 - they are close but not equal, which is why a "500 GB" drive shows up as roughly 465 GiB in your operating system.

KB vs KiB: 1000 or 1024?
SI units (KB, MB, GB, TB) are powers of 1000. Binary units (KiB, MiB, GiB, TiB) are powers of 1024. Storage manufacturers advertise in decimal units while operating systems often report binary units, which is why drives appear "smaller" than advertised. When precision matters, name the unit explicitly.
