Kilobytes (kB) to Bits (bit) Conversion
Kilobytes
The kilobyte (kB) is a unit of digital information equal to 1,000 bytes in the SI decimal system. In the binary convention historically used by operating systems, 1,024 bytes was called a kilobyte — now formally named a kibibyte (KiB). Hard drive manufacturers use the decimal definition, while operating systems historically used binary values, making a "500 GB" drive appear as roughly 465 GB in Windows. Plain-text documents, small images, and configuration files are measured at the kilobyte scale.
Bits
The bit (binary digit) is the fundamental unit of information in computing and digital communications, representing a single binary value — either 0 or 1. Formalised by Claude Shannon in his landmark 1948 paper "A Mathematical Theory of Communication," the bit is the atomic unit of information theory: the information content of a fair coin flip is exactly 1 bit. All digital data — text, images, audio, video, and executable code — is ultimately stored and transmitted as sequences of bits.
