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

About kilobyte and byte
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).
Byte: A byte is 8 bits — the basic addressable unit of computer storage.
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 byte are in 1 kilobyte?
- 1 kilobyte = 1,000 byte (B).
- How do I convert kilobyte to byte?
- Multiply the number of kilobyte by 1,000. For example, 10 kilobyte = 10 × 1,000 = 10,000 byte.
- How many kilobyte are in 1 byte?
- 1 byte = 0.001 kilobyte.
- Which is bigger, kilobyte or byte?
- 1 kilobyte equals 1,000 byte, so a kilobyte is the larger unit.
