KiB to Bytes Converter
Convert kibibytes to bytes — exactly 1,024 bytes to the kibibyte. Results update as you type; exact factors shown.
One kibibyte (2¹⁰) is 1,024 bytes — see the exact factor, not a rounded rule of thumb.
How the kib to bytes converter works
Storage converts through the byte (8 bits). Drive makers and network speeds use decimal prefixes (1 GB = 10⁹ bytes); operating systems often report binary units (1 GiB = 2³⁰ = 1,073,741,824 bytes) — sometimes labelled "GB". The gap is 7.4% at the gigabyte and 10% at the terabyte.
The US uses customary units (US gallon, short ton, °F) in daily life; NIST SP 811 gives the exact SI factors.

FAQFrequently asked questions about data conversion
How many bytes in a kibibyte?
Exactly 1,024 — two to the tenth.
How is that different from a kilobyte?
A kilobyte is 1,000 bytes. The binary prefixes were standardised in 1998 to end the ambiguity.
What is 4 KiB?
4,096 bytes — the standard memory page and disk block size.
Why 1,024?
Because memory is addressed in powers of two, and 2¹⁰ is the nearest to a thousand.
What does Windows call it?
KB — it reports binary sizes with decimal names, which is the source of most of the confusion.
