Work out bytes to kilobytes instantly with clear inputs, formula shown and shareable results.
Converting Bytes to Kilobytes is one multiplication: a single B is 0.001 kB, so the amount is scaled by that factor. Reversing the direction divides by the same factor. The factor is an exact definition rather than a rounded figure, so the result stays precise at any magnitude. This uses the SI kilobyte of 1000 bytes. For the 1024-byte binary unit, use the kibibyte in the multi-unit storage converter.
Bytes → Kilobytes
kB = B × 0.001
Kilobytes → Bytes
B = kB ÷ 0.001
One B equals 0.001 kB. That value is exact by definition.
Divide by 0.001 rather than multiplying, or flip the direction selector which does it for you.
