Gigabytes (GB) to Megabits (Mbit) 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.
Megabits
The megabit (Mbit) is a unit of digital information equal to exactly 1,000,000 bits (10⁶ bits). It is the standard unit for expressing internet connection speeds: a "100 Mbps" broadband connection transfers 100 million bits per second, equivalent to 12.5 megabytes (MB/s). This factor-of-8 difference between megabits and megabytes is a frequent source of consumer confusion when comparing marketed connection speeds against actual file download rates.
