Kilobyte (KB): One Thousand Bytes (1,000)

Kilobyte (KB)

A kilobyte commonly known by its abbreviation KB, is a unit of computer storage. 1KB equals 1024 bytes or one thousand bytes (1,000) depending on the context. Hard drives storage capacity used to be measured in kilobytes, then megabytes and now in gigabytes (eg. 80GB or 200GB). Computer memory used to be measured in kilobytes too, however megabytes and gigabytes have superseded.

Floppy disks hold 1.44MB or 1,440 Kilobytes.

One common confusion with kilobytes is that most hard drive manufacturers say that 1KB = 1,000 bytes, however operating systems and computer memory say that 1KB = 1,024 bytes.

Hopefully the table below will make clear how much a kilobyte is actually worth.
