Kilobytes (kB) to Gigabytes (GB) 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.
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.
