Gigabytes (GB) to Bytes (B) 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.
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.
