Bits to Megabytes formula
The factor from bits to megabytes is 1.25e-07.
MB = bit × 1.25e-07
Why this factor: the bit and the megabyte are both defined against the byte, so dividing one definition by the other gives 1.25e-07 directly. Both definitions are set out in full below.
To go the other way, divide by 1.25e-07 — or use the Megabytes to Bits converter, which is the same calculation reversed.
Worked example
Take 64 bit and multiply by the factor 1.25e-07: the result is 8e-06 MB.
64 bit × 1.25e-07 = 8e-06 MB
The converter above does this for any value you type, in either direction.
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.
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.
Bits vs Megabytes
The bit and the megabyte 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 megabytes are in a bit?
One bit equals 1.25e-07 megabytes.
What is the formula to convert bits to megabytes?
