Convert Kibibytes to Bytes (KiB to B)
1 kibibyte (KiB) = 1024 bytes (B). 1 B = 0.0009765625 KiB. Example: 15 KiB = 15 × 1024 = 15360 B.

How to Convert Kibibyte to Byte
- 1 KiB = 1024 B
- 1 B = 0.0009765625 KiB
- Example: convert 15 KiB to B: 15 KiB = 15 × 1024 B = 15360 B
Formula
B = KiB × 1024
Derivation from SI units:
- 1 KiB = 2¹⁰ bytes = 1024 bytes.
- 1 byte = 8 bits (an octet).
- 1 KiB = 8192 bit ÷ 8 bit per B = 1024 B
Both units are defined exactly, so the factor is exact. Kibibyte definition: kibibyte; Byte definition: byte.
Worked examples
- A reading of 16 KiB converts to 16384 B.
16 KiB × 1024 = 16384 B - A value of 128 KiB is 131072 B.
128 KiB × 1024 = 131072 B
