PB to MB Converter

How to convert petabytes to megabytes

FormulaMB = PB × 1,000,000,000

Multiply the value in petabytes by 1,000,000,000. To go the other way, multiply by 1×10⁻⁹ (or divide by 1,000,000,000).

A petabyte is larger than a megabyte: one petabyte contains 1,000,000,000 megabytes.

About the units

Petabyte (PB)

The petabyte (PB) is a unit of data storage in the International System of Units (SI). One petabyte equals 8×10¹⁵ 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 petabyte?

There are 1,000,000,000 megabytes in one petabyte, and this value is exact by definition.

How do I convert petabytes to megabytes?

Multiply the number of petabytes by 1,000,000,000. For example, 10 PB × 1,000,000,000 = 10,000,000,000 MB.

How many petabytes are in one megabyte?

One megabyte equals 1×10⁻⁹ petabytes. That is the reverse factor, 1 ÷ 1,000,000,000.

What is 10 petabytes in megabytes?

10 PB = 10,000,000,000 MB.

Is this PB 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.
