Convert Byte to Kilobyte
1 byte = 0.001 kilobyte (KB). For example, 10 byte = 0.01 kilobyte and 100 byte = 0.1 kilobyte. Type any value below to convert byte to kilobyte both ways — it runs entirely in your browser.
Byte to Kilobyte conversion formula
To convert byte to kilobyte, multiply by 0.001:
kilobyte = byte × 0.001
Going the other way, 1 kilobyte = 1,000 byte, so
byte = kilobyte × 1,000.

| 1000 B = 1 KB | 1000 KB = 1,000,000 B |
About byte and kilobyte
Byte: A byte is 8 bits — the basic addressable unit of computer storage.
Kilobyte: A kilobyte is 1,000 bytes in the SI/decimal convention used by storage makers and networks. The 1,024-byte unit is the kibibyte (KiB).
This converter uses the decimal (SI) convention for KB/MB/GB/TB (1 KB = 1,000 bytes), as used by storage manufacturers and networks. The binary units — KiB, MiB, GiB (1 KiB = 1,024 bytes) — are listed separately, because operating systems often label binary sizes with the decimal names.
Frequently asked questions
- How many kilobyte are in 1 byte?
- 1 byte = 0.001 kilobyte (KB).
- How do I convert byte to kilobyte?
- Multiply the number of byte by 0.001. For example, 10 byte = 10 × 0.001 = 0.01 kilobyte.
- How many byte are in 1 kilobyte?
- 1 kilobyte = 1,000 byte.
- Which is bigger, byte or kilobyte?
- 1 kilobyte equals 1,000 byte, so a kilobyte is the larger unit.
