KiB to KB Converter
Convert kibibytes to kilobytes — 1,024 bytes against 1,000. Results update as you type; exact factors shown.
One kibibyte (2¹⁰) is 1.024 kilobyte (10³) — see the exact factor, not a rounded rule of thumb.
How the kib to kb 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.
Australia is fully metric under the National Measurement Act 1960; imperial units appear only in trade with the US and in older documents.

FAQFrequently asked questions about data conversion
What is the difference between KiB and KB?
A kibibyte is 1,024 bytes; a kilobyte is 1,000. The binary prefixes were standardised in 1998 precisely to end the ambiguity.
What is 1 KiB in KB?
1.024 KB.
Which does Windows use?
Binary sizes labelled with decimal names — what it calls KB is really KiB.
Which does storage marketing use?
Decimal, which is why a drive always looks smaller once installed.
What is 1,024 KiB?
One mebibyte, or 1.049 MB.
