About Converting Megabits to MiBs
Megabit and MiB 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
mibs = megabits × 0.119209289551
This factor comes from each unit's defined relationship to the category's base unit: 1 megabit equals 1000000 base units, and 1 mib equals 8388608 base units, so dividing one by the other gives the direct megabit-to-mib factor of 0.119209289551.
Simple example
1 Mb × 0.1192092896 = 0.1192092896 MiB
1 megabit = 0.1192092896 mibs.
Real-world example
500 Mb × 0.1192092896 = 59.60464478 MiB
500 megabits = 59.60464478 mibs.

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.

MiB digital storage unit.

Frequently asked questions
How many mibs are in 1 megabit?
1 megabit equals 0.1192092896 mibs, using the exact defined conversion factor rather than an estimate.
How do I convert megabit to mib?
Multiply the megabit value by 0.1192092896. The converter above does this instantly to whatever precision you set.
How do I convert mib back to megabit?
Use the reverse factor: 1 mib equals 8.388608 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 mib?
MiB (MiB) is a unit of digital storage.
