Bytes to MB Converter

How to convert bytes to megabytes

FormulaMB = B × 0.000001

Multiply the value in bytes by 0.000001. To go the other way, multiply by 1,000,000 (or divide by 0.000001).

A byte is smaller than a megabyte: it takes 1,000,000 bytes to make one megabyte.

About the units

Byte (B)

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

Megabyte (MB)

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

Frequently asked questions

How many megabytes are in one byte?

There are 0.000001 megabytes in one byte, and this value is exact by definition.

How do I convert bytes to megabytes?

Multiply the number of bytes by 0.000001. For example, 10 B × 0.000001 = 0.00001 MB.

How many bytes are in one megabyte?

One megabyte equals 1,000,000 bytes. That is the reverse factor, 1 ÷ 0.000001.

What is 10 bytes in megabytes?

10 B = 0.00001 MB.

Is this B to MB 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.
