About kibibyte and kilobyte

Kibibyte: A kibibyte is exactly 1,024 bytes (2¹⁰) — the binary (IEC) unit operating systems often label "KB".

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.
