How to convert kilobytes to bytes

To convert kilobytes to bytes, multiply by 1000. For example, 5 KB × 1000 = 5000 bytes. Going the other way, divide bytes by 1000 to get kilobytes.

In binary, 1 KiB = 1024 bytes. Operating systems sometimes use binary while storage manufacturers use decimal.

1 KB = 1000 bytes (decimal). A byte is the basic unit of digital storage — equal to 8 bits. Kilobytes are used for small files like text documents, emails, and small images.
