Bits to MB Converter

How to convert bits to megabytes

FormulaMB = b × 1.25×10⁻⁷

Because one megabyte equals 8,000,000 bits, you can also divide: MB = b ÷ 8,000,000.

A bit is smaller than a megabyte: it takes 8,000,000 bits to make one megabyte.

About the units

Bit (b)

A single binary digit, 0 or 1.

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 bit?

There are 1.25×10⁻⁷ megabytes in one bit, and this value is exact by definition.

How do I convert bits to megabytes?

Multiply the number of bits by 1.25×10⁻⁷. For example, 10 b × 1.25×10⁻⁷ = 0.00000125 MB.

How many bits are in one megabyte?

One megabyte equals 8,000,000 bits. That is the reverse factor, 1 ÷ 1.25×10⁻⁷.

What is 10 bits in megabytes?

10 b = 0.00000125 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.
