About Converting Bytes to Megabits
Byte and Megabit are everyday digital-storage units, used for everything from file sizes and app downloads to storage device capacity and mobile data allowances. Byte is typically associated with universal in computing, while Megabit is typically associated with used worldwide for network and internet speed ratings.
Formula
megabits = bytes × 0.000008
This factor comes from each unit's defined relationship to the category's base unit: 1 byte equals 8 base units, and 1 megabit equals 1000000 base units, so dividing one by the other gives the direct byte-to-megabit factor of 0.000008.
Simple example
1 B × 0.000008 = 0.000008 Mb
1 byte = 0.000008 megabits.
Real-world example
500 B × 0.000008 = 0.004 Mb
500 bytes = 0.004 megabits.
Conversion table
| Byte (B) | Megabit (Mb) |
|---|---|
| 1 B | 0.000008 Mb |
| 8 B | 0.000064 Mb |
| 16 B | 0.000128 Mb |
| 64 B | 0.000512 Mb |
| 256 B | 0.002048 Mb |
| 1,000 B | 0.008 Mb |
Reverse conversion: Megabit to Byte
0.000008 Mb × 125000 = 1 B
0.000008 megabits = 1 byte.
bytes = megabits × 125000

Byte vs. Megabit
| Aspect | Byte | Megabit |
|---|---|---|
| Family | Base digital storage unit | Decimal (SI-prefixed) digital unit |
| Typical use | Fundamental unit for file sizes and memory addressing | Internet connection speed advertising (Mbps) |
| Where it's used | Universal in computing | Used worldwide for network and internet speed ratings |
Understanding the Byte
Byte (B) measures digital storage. A byte is 8 bits, the standard unit for addressing a single character of text in most computer architectures. It is classified as a Base digital storage unit.
Where it's used: Universal in computing
Uses of the Byte today
- Fundamental unit for file sizes and memory addressing
- Base unit from which all larger storage units (KB, MB, GB) are derived
History of the Byte
The byte emerged in the 1950s-60s as computer architectures converged on 8 bits as a practical size for representing a single character; IBM's System/360 (1964) was influential in cementing the 8-bit byte as an industry standard.
Historical origin. Byte was not the invention of a single named person; it developed through the process described above.
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.

Frequently asked questions
How many megabits are in 1 byte?
1 byte equals 0.000008 megabits, using the exact defined conversion factor rather than an estimate.
How do I convert byte to megabit?
Multiply the byte value by 0.000008. The converter above does this instantly to whatever precision you set.
How do I convert megabit back to byte?
Use the reverse factor: 1 megabit equals 125,000 bytes. You can also use the swap control in the converter above to flip the direction instantly.
What is a byte?
Byte (B) measures digital storage. A byte is 8 bits, the standard unit for addressing a single character of text in most computer architectures. It is classified as a Base digital storage unit.
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.
Is the byte to megabit conversion exact?
Yes. Both byte and megabit are defined by fixed standards rather than physical artifacts, so the factor of 0.000008 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 byte still used today?
Universal in computing
