About Converting GiBs to Megabits
GiB and Megabit are everyday digital-storage units, used for everything from file sizes and app downloads to storage device capacity and mobile data allowances. Specifically: GiB digital storage unit, and megabit digital storage unit.
Formula
megabits = gibs × 8589.934592
This factor comes from each unit's defined relationship to the category's base unit: 1 gib equals 8589934592 base units, and 1 megabit equals 1000000 base units, so dividing one by the other gives the direct gib-to-megabit factor of 8589.934592.
Simple example
1 GiB × 8589.934592 = 8,589.934592 Mb
1 gib = 8,589.934592 megabits.
Real-world example
500 GiB × 8589.934592 = 4,294,967.296 Mb
500 gibs = 4,294,967.296 megabits.

Understanding the GiB (GiB)
GiB digital storage unit.
Understanding the Megabit
Megabit (Mb) measures digital storage/transfer. A megabit is 1,000,000 bits (125,000 bytes) under the decimal convention used for network speeds. It is classified as a Decimal (SI-prefixed) digital unit.
Where it's used: Used worldwide for network and internet speed ratings
Megabits vs. megabytes. Internet speeds are quoted in megabits per second (Mbps), while file sizes are quoted in megabytes (MB) — 8 megabits equal 1 megabyte, so a '100 Mbps' connection downloads at up to about 12.5 MB per second.
Uses of the Megabit today
- Internet connection speed advertising (Mbps)
- Network bandwidth measurement
History of the Megabit
Network speeds have conventionally been quoted in bits rather than bytes since early telecommunications measured signal rate in bits per second; this convention carried into modern internet service marketing, which is why connection speeds (Mbps) and file sizes (MB) use different base units, a frequent source of consumer confusion.
Historical origin. Megabit was not the invention of a single named person; it developed through the process described above.
Megabit — sources
- IEC 80000-13 — Defines bit-based units distinct from byte-based units.
