About the units

Megabyte (MB)

1,000,000 bytes (decimal). A minute of MP3 audio is about 1 MB. One megabyte equals 8,000,000 bits (b).

Byte (B)

Eight bits; the basic addressable unit of memory. One byte equals 8 bits (b).

Frequently asked questions

How many bytes are in one megabyte?

There are 1,000,000 bytes in one megabyte, and this value is exact by definition.

How do I convert megabytes to bytes?

Multiply the number of megabytes by 1,000,000. For example, 10 MB × 1,000,000 = 10,000,000 B.

How many megabytes are in one byte?

One byte equals 0.000001 megabytes. That is the reverse factor, 1 ÷ 1,000,000.

What is 10 megabytes in bytes?

10 MB = 10,000,000 B.

Is this MB to B converter accurate?

Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
