Kilobytes to kibibyte Conversion
1 kilobytes (kB) is equal to 0.9765625 kibibyte (KiB).
1 kB = 0.9765625 KiB
or
1 KiB = 1.024 kB
Formula
To convert a digital storage from kilobytes (kB) to kibibyte (KiB), divide the digital storage in kilobytes by 1.024
d(KiB) = d(kB) / 1.024
Examples:
Convert 256 kilobytes to kibibyte:
d(KiB) = 256kB / 1.024 = 250 KiB
