Bytes to KB Converter
Convert bytes to kilobytes — a thousand bytes to the kilobyte on the decimal definition. Results update as you type; exact factors shown.
One byte is 0.001 kilobyte (10³) — see the exact factor, not a rounded rule of thumb.
How the bytes 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.
