How to Convert Bytes to Megabits
To convert bytes to megabits, multiply the data size by the following conversion ratio: 0.000008 megabits/byte.
Since one byte is equal to 0.000008 megabits, you can use this simple formula to convert:
The data size in megabits is equal to the data size in bytes multiplied by 0.000008.
For example, here's how to convert 5 bytes to megabits using the formula above.
How Many Megabits Are in a Byte?
There are 0.000008 megabits in a byte, which is why we use this value in the formula above.
Our byte to megabit calculator automatically converts your data size measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Bytes and megabits are both units used to measure data size. Keep reading to learn more about each unit.
What Is a Byte?
8 binary bits. It serves as a primary reference unit for measuring data size across scientific and practical applications. [1]
The byte is classified as an IEC binary unit of data size. Bytes can be abbreviated as B; for example, 1 byte can be written as 1 B.
As the primary coherent reference unit for data size in this category, all other data size units are mathematically anchored to the byte (B).
In practice, bytes (B) are widely used across standard data size applications within IEC binary workflows, engineering documentation, and technical data sheets.
What Is a Megabit?
A megabit is a unit of data size equal to 125,000 bytes (B), the base unit for data size. Equal to 1,000,000 bits (125 KB). [2]
The megabit is classified as a metric and SI-compatible unit of data size. Megabits can be abbreviated as Mb; for example, 1 megabit can be written as 1 Mb.
In the metric system, "mega" is the standard SI prefix for millions, or 10⁶. This makes the megabit (Mb) a convenient decimal multiple of the byte (B).
In practice, megabits (Mb) are widely used across large-scale industrial, bulk, and macro-level data size specifications within SI metric workflows, engineering documentation, and technical data sheets.
When converting data size between bytes (B) and megabits (Mb), keep full floating-point precision (1 B = 0.000008 Mb; 1 Mb = 125,000 B) during intermediate calculations and round only the final megabit figure to match your instrument tolerance.
