Bytes to Kilobytes Converter
Convert bytes to kilobytes instantly. Type a value, change either unit, or press swap to go the other way. 1 byte = 0.001 kilobytes.
1 byte = 0.001 kilobytes
How to convert bytes to kilobytes
kilobytes = bytes × 0.001
To convert bytes to kilobytes, multiply the value by 0.001. To go back from kilobytes to bytes, divide by the same number (or multiply by 1,000).
Worked examples
- 500 B: 500 × 0.001 = 0.5 KB
- 1,000 B: 1,000 × 0.001 = 1 KB
- 1,024 B: 1,024 × 0.001 = 1.024 KB
Divide by 1,000 (or 1,024 for the binary kibibyte). 5,000 bytes is 5 KB.

When you need to convert bytes to kilobytes
Programming, file-system tools and web-performance reports show sizes in bytes, but humans read kilobytes more easily. Converting helps you understand how big a web page, image or document really is.
About the units
Byte (B)
A byte is eight bits and holds one character of basic text. It is the base unit for file sizes.
Kilobyte (KB)
In the decimal (SI) system a kilobyte is 1,000 bytes. A short text email is a few kilobytes.
Frequently asked questions
How do I convert bytes to kilobytes?
Multiply the number of bytes by 0.001. For example, 10 bytes × 0.001 = 0.01 kilobytes.
How many kilobytes are in one byte?
There are 0.001 kilobytes in one byte.
How many bytes are in one kilobyte?
There are 1,000 bytes in one kilobyte.
How many characters fit in 1 KB?
In plain ASCII text each character is one byte, so 1 KB (1,000 bytes) holds about 1,000 characters, roughly 170 English words.
Can I convert other data units with this tool?
Yes. Use the From and To drop-downs in the converter to choose any data unit, or press the swap button to reverse the conversion. All calculations use internationally defined conversion factors.
