About Converting Megabits to GiBs
Megabit and GiB are everyday digital-storage units, used for everything from file sizes and app downloads to storage device capacity and mobile data allowances. Megabit is most often used for internet connection speed advertising (mbps).
Formula
gibs = megabits × 0.000116415321827
This factor comes from each unit's defined relationship to the category's base unit: 1 megabit equals 1000000 base units, and 1 gib equals 8589934592 base units, so dividing one by the other gives the direct megabit-to-gib factor of 0.000116415321827.
Simple example
1 Mb × 0.0001164153218 = 0.0001164153 GiB
1 megabit = 0.0001164153 gibs.
Real-world example
500 Mb × 0.0001164153218 = 0.0582076609 GiB
500 megabits = 0.0582076609 gibs.

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.
Understanding the GiB (GiB)
GiB digital storage unit.

Frequently asked questions
How many gibs are in 1 megabit?
1 megabit equals 0.0001164153 gibs, using the exact defined conversion factor rather than an estimate.
How do I convert megabit to gib?
Multiply the megabit value by 0.0001164153218. The converter above does this instantly to whatever precision you set.
How do I convert gib back to megabit?
Use the reverse factor: 1 gib equals 8,589.934592 megabits. You can also use the swap control in the converter above to flip the direction instantly.
What is a 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.
What is a gib?
GiB (GiB) is a unit of digital storage.
