About these units
Gigabyte (GB)
A gigabyte is 1,073,741,824 bytes (2³⁰) in binary notation, or 1,000,000,000 bytes in decimal form. Gigabytes serve as one of the most common units of modern computing: RAM capacities, smartphone storage, software downloads, and video file sizes frequently range from a few GB to dozens of gigabytes. The gigabyte era represented a massive shift in capability—allowing high-resolution multimedia, complex software, virtual machines, and databases to flourish. While once enormous, gigabytes are now considered routine, illustrating the exponential growth of digital storage.
Kilobyte (10^3 bytes) (kB (10^3))
A decimal kilobyte equals 1,000 bytes, reflecting the SI prefix kilo = 10³. Storage device manufacturers standardize on this definition because it scales cleanly and simplifies marketing and specification. This creates a mismatch with binary kilobytes (1,024 bytes) historically used in RAM and file systems. As storage capacities grew, this discrepancy became increasingly noticeable, leading standards bodies to promote explicit binary prefixes (KiB, MiB) for clarity. Despite these efforts, decimal kilobytes remain dominant in contexts such as hard drives, flash memory packaging, and communication standards.
