How to convert kilobyte to byte

In decimal units 1 KB is 1,000 bytes. The binary kibibyte (KiB) is 1,024 bytes and is common in operating systems and memory sizes.

Formula

B = KB × 1,000

Worked example

4 KB × 1,000 = 4,000 B

A 4 KB text file is 4,000 bytes, and a 50 KB web page is 50,000 bytes.

In SI units a kilobyte is 1,000 bytes; a kibibyte (KiB) is 1,024 bytes.

Computers address memory in powers of 2, so 1,024 (2^10) was used informally, and the IEC introduced KiB, MiB and GiB to remove the ambiguity.

1 kilobyte = 1,000 byte (KB to B).

B = KB × 1,000. For example, 4 KB × 1,000 = 4,000 B.

Use the reverse converter: 1 byte = 0.001 kilobyte. Check: 4,000 B converts back to 4 KB.
