Bytes to Kilobytes (B to kB) Converter

Bytes to Kilobytes

1 byte = 0.001 kilobytes. To convert bytes (B) to kilobytes (kB), multiply by 0.001.

Bytes (B)

Kilobytes (kB)

How to convert bytes to kilobytes

kB = B × 0.001

Example: convert 8 bytes to kilobytes.
8 B × 0.001 = 0.008 kB

The same relationship in reverse: 1 kilobyte = 1,000 bytes, so you can also divide by 1,000. Need the other direction? Use the kilobytes to bytes converter.

You will typically need this conversion for programming, memory and file-format limits.

About the units

Byte (B)

Eight bits. One byte stores one ASCII character.

Kilobyte (kB)

1,000 bytes (SI). Some older software uses "KB" to mean 1,024 bytes — that is properly a kibibyte (KiB).

Frequently asked questions

How many kilobytes are in a byte?

1 byte = 0.001 kilobytes. Going the other way, 1 kilobyte = 1,000 bytes.

How do I convert bytes to kilobytes?

To convert bytes to kilobytes, multiply by 0.001. The formula is kB = B × 0.001.

What is 8 B in kB?

8 bytes is 0.008 kilobytes (8 B × 0.001 = 0.008 kB).
