About Converting Megabits to Terabits
Megabit and Terabit 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
terabits = megabits × 0.000001
This factor comes from each unit's defined relationship to the category's base unit: 1 megabit equals 1000000 base units, and 1 terabit equals 1e+12 base units, so dividing one by the other gives the direct megabit-to-terabit factor of 0.000001.
Simple example
1 Mb × 0.000001 = 0.000001 Tb
1 megabit = 0.000001 terabits.
Real-world example
500 Mb × 0.000001 = 0.0005 Tb
500 megabits = 0.0005 terabits.
Conversion table
| Megabit (Mb) | Terabit (Tb) |
|---|---|
| 1 Mb | 0.000001 Tb |
| 8 Mb | 0.000008 Tb |
| 16 Mb | 0.000016 Tb |
| 64 Mb | 0.000064 Tb |
| 256 Mb | 0.000256 Tb |
| 1,000 Mb | 0.001 Tb |
Reverse conversion: Terabit to Megabit
0.000001 Tb × 1000000 = 1 Mb
0.000001 terabits = 1 megabit.
megabits = terabits × 1000000

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

Frequently asked questions
How many terabits are in 1 megabit?
1 megabit equals 0.000001 terabits, using the exact defined conversion factor rather than an estimate.
How do I convert megabit to terabit?
Multiply the megabit value by 0.000001. The converter above does this instantly to whatever precision you set.
How do I convert terabit back to megabit?
Use the reverse factor: 1 terabit equals 1,000,000 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 terabit?
Terabit (Tb) is a unit of digital storage.
Is the megabit to terabit conversion exact?
Yes. Both megabit and terabit are defined by fixed standards rather than physical artifacts, so the factor of 0.000001 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?
