Gigabytes (GB) to Bits (bit) Conversion
Gigabytes
The gigabyte (GB) is a unit of digital information equal to 1,000,000,000 bytes (10⁹ bytes) in SI decimal, or 1,073,741,824 bytes in binary convention. It is the dominant unit for consumer storage — smartphone internal storage, USB drives, and SD cards are sold in gigabytes. One hour of standard HD streaming consumes approximately 3 GB; one hour of 4K video requires 7–15 GB depending on encoding. Monthly mobile data plans are universally priced per gigabyte.
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.
