Green letter K and pink letter B.

Abbreviated as K, kB, KB, K-byte, and KByte, a kilobyte was initially equal to 1,024 bytes because of base 2. However, in 1998, the IEC (International Electrotechnical Commission) approved standard 60027-2, which defined 1,024 bytes as a kibibyte and not a kilobyte. Today, a kilobyte equals 1,000 bytes, and a kibibyte equals 1,024 bytes.


When the "b" is lowercase (Kb), this refers to a kilobit.

What comes before a kilobyte?

A byte comes before a kilobyte.

What comes after a kilobyte?

A megabyte comes after a kilobyte.

Converting kilobytes to another unit

Below is a listing of kilobyte values where a kilobyte is considered 1,000 bytes. Using this chart, you can find how many kilobytes are in other measurements. For example, you can see 1,000 kilobytes in a megabyte. For measurements that are smaller than a kilobyte, the decimal value is shown.


See our kibibyte (KiB) definition for a listing of kibibyte values where a kibibyte equals 1,024 bytes.
