Kilobytes to Bytes Converter

Convert kilobytes (kB) to bytes (B), with the formula, a conversion table and exact factors.

Change the values and press Calculate to work out your own figures.

Enter an amount of data, choose its unit and the unit you want. The answer is exact until it is shown, and the same value appears in every other unit.

A number, fraction (3/8), mixed number (1 1/2), scientific notation (2.5e6) or a simple sum such as 2*3.
The unit you want the answer in. Swap exchanges the two units.

1 kB = 1,000 B

Show the working
  1. 1 kB = 1000 B
  2. 1 × 1000 = 1000 B

How to convert kilobytes to bytes

1 kB = 1,000 B, so multiply by 1,000 to go from kilobytes to bytes. Going the other way, 1 B = 0.001 kB.

B = kB × 1,000
kB = B × 0.001

Worked example:

1 kB = 1000 B
5 × 1000 = 5000 B

About the units

Kilobytes (kB)
Kilobytes, a metric unit. Decimal (SI) kilobyte = 1000^1 bytes. Many operating systems label the binary kibibyte (KiB) as 'kB'. Definition: NIST: Prefixes for binary multiples (IEC 80000-13).
Bytes (B)
Bytes, a specialised unit. Definition: NIST: Prefixes for binary multiples (IEC 80000-13).
