Bits (bit) to Bytes (B) Conversion
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.
Bytes
The byte is a unit of digital information equal to exactly 8 bits, capable of representing 256 distinct values (2⁸). The 8-bit grouping became standard in the 1960s because it was sufficient to encode the 128-character ASCII set with one bit to spare for error detection. The byte is the standard unit for measuring file sizes, memory capacity, and storage media. In networking, data transfer rates are expressed in bits per second — divide by 8 to convert to bytes per second.
