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 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.
