About Converting PiBs to Megabits
PiB 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: PiB digital storage unit, and megabit digital storage unit.
Formula
megabits = pibs × 9007199254.74
This factor comes from each unit's defined relationship to the category's base unit: 1 pib equals 9.007199e+15 base units, and 1 megabit equals 1000000 base units, so dividing one by the other gives the direct pib-to-megabit factor of 9007199254.74.
Simple example
1 PiB × 9007199255 = 9,007,199,255 Mb
1 pib = 9,007,199,255 megabits.
Real-world example
500 PiB × 9007199255 = 4.5036e+12 Mb
500 pibs = 4.5036e+12 megabits.

Reverse conversion: Megabit to PiB
1 Mb × 1.110223e-10 = 1.110223e-10 PiB
1 megabit = 1.110223e-10 pibs.
pibs = megabits × 1.110223e-10

Understanding the PiB (PiB)
PiB 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.

Frequently asked questions
How many megabits are in 1 pib?
1 pib equals 9,007,199,255 megabits, using the exact defined conversion factor rather than an estimate.
How do I convert pib to megabit?
Multiply the pib value by 9007199255. The converter above does this instantly to whatever precision you set.
How do I convert megabit back to pib?
Use the reverse factor: 1 megabit equals 1.110223e-10 pibs. You can also use the swap control in the converter above to flip the direction instantly.
What is a pib?
PiB (PiB) is a unit of digital storage.
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.
