How to use
- Enter a value in the Megabytes field.
- The Bits figure appears immediately — no button to press.
- Typing in the Bits field converts back to Megabytes the same way.
- Use the reference table for the values that come up most often.
Megabytes to Bits formula
To convert megabytes to bits, multiply by 8000000.
bit = MB × 8000000
Why this factor: the megabyte and the bit are both defined against the byte, so dividing one definition by the other gives 8000000 directly. Both definitions are set out in full below.
To go the other way, divide by 8000000 — or use the Bits to Megabytes converter, which is the same calculation reversed.
Worked example
Take 64 MB and multiply by the factor 8000000: the result is 512000000 bit.
64 MB × 8000000 = 512000000 bit
The converter above does this for any value you type, in either direction.
What is a megabyte?
A megabyte is one million bytes, the familiar unit for photos, songs and app sizes.
Definition: Exactly 1,000,000 bytes under SI prefixes. The binary mebibyte (MiB) is 1,048,576 bytes.
Where it is used: Photo and audio file sizes, app downloads, and mobile data allowances.
What is a bit?
A bit is the smallest unit of digital information — a single binary digit, either 0 or 1.
Definition: One eighth of a byte. The name is a contraction of 'binary digit'.
Where it is used: Network and connection speeds, which are always quoted in bits per second.
Worth knowing: Lowercase 'b' is bits, uppercase 'B' is bytes. A 100 Mb/s connection delivers about 12.5 MB/s.
Megabytes vs Bits
The megabyte and the bit belong to the same family of units, so converting between them is usually a matter of shifting a decimal point or applying a small whole-number factor.
Frequently asked questions
How many bits are in a megabyte?
One megabyte equals 8000000 bits.
What is the formula to convert megabytes to bits?
Multiply the number of megabytes by 8000000. To reverse it, divide by 8000000 instead.
How do I convert bits back to megabytes?
Divide by 8000000, which is the same as multiplying by 1.25e-07.
How many bits are in 10 megabytes?
10 MB works out to 80000000 bit.
Is there anything to watch out for with bits?
Lowercase 'b' is bits, uppercase 'B' is bytes. A 100 Mb/s connection delivers about 12.5 MB/s.
How is the megabyte defined?
Exactly 1,000,000 bytes under SI prefixes. The binary mebibyte (MiB) is 1,048,576 bytes.
