How to convert
Exact conversion factors in both directions, plus a worked example.
1 B = 0.001 KB
1 KB = 1000 B
To convert byte to kilobyte, multiply by 0.001.
To convert kilobyte to byte, multiply by 1000.
Example: convert 10 B to KB
10 × 0.001 = 0.01 KB
About these units
Short background on the units used in this conversion.
Kilobyte (KB)
A decimal kilobyte (KB) is exactly 1,000 bytes — the SI-style prefix used by storage vendors and many operating systems.
Decimal KB and MB appear on USB drive labels, broadband speed marketing, and macOS storage displays.
Frequently asked questions
How many kilobytes are in one byte?
One byte equals 0.001 kilobytes. Multiply your bytes value by 0.001 to convert to kilobytes.
What is the conversion formula?
KB = B × 0.001The reverse is
B = KB × 1,000, using the same exact factors as this converter.Is this Byte to Kilobyte converter private?
Yes. All calculations run locally in your browser. Nothing you type is sent to a server.
