About Converting Megabits to Exabits
Megabit and Exabit 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
exabits = megabits × 1e-12
This factor comes from each unit's defined relationship to the category's base unit: 1 megabit equals 1000000 base units, and 1 exabit equals 1e+18 base units, so dividing one by the other gives the direct megabit-to-exabit factor of 1e-12.
Simple example
1 Mb × 1e-12 = 1e-12 Eb
1 megabit = 1e-12 exabits.
Real-world example
500 Mb × 1e-12 = 5e-10 Eb
500 megabits = 5e-10 exabits.
Conversion table
| Megabit (Mb) | Exabit (Eb) |
|---|---|
| 1 Mb | 1e-12 Eb |
| 8 Mb | 8e-12 Eb |
| 16 Mb | 1.6e-11 Eb |
| 64 Mb | 6.4e-11 Eb |
| 256 Mb | 2.56e-10 Eb |
| 1,000 Mb | 1e-9 Eb |
Reverse conversion: Exabit to Megabit
1e-12 Eb × 1e+12 = 1 Mb
1e-12 exabits = 1 megabit.
megabits = exabits × 1e+12

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 Exabit (Eb)
Exabit digital storage unit.
Megabit — sources
- IEC 80000-13 — Defines bit-based units distinct from byte-based units.

Frequently asked questions
How many exabits are in 1 megabit?
1 megabit equals 1e-12 exabits, using the exact defined conversion factor rather than an estimate.
How do I convert megabit to exabit?
Multiply the megabit value by 1e-12. The converter above does this instantly to whatever precision you set.
How do I convert exabit back to megabit?
Use the reverse factor: 1 exabit equals 1e+12 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 exabit?
Exabit (Eb) is a unit of digital storage.
Is the megabit to exabit conversion exact?
Yes. Both megabit and exabit are defined by fixed standards rather than physical artifacts, so the factor of 1e-12 used above is exact to as many digits as you choose to display.
What is the difference between 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.
Where is the megabit still used today?
