MB to PB Converter

How to convert megabytes to petabytes

FormulaPB = MB × 1×10⁻⁹

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

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

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).

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).

Frequently asked questions

How many petabytes are in one megabyte?

There are 1×10⁻⁹ petabytes in one megabyte, and this value is exact by definition.

How do I convert megabytes to petabytes?

Multiply the number of megabytes by 1×10⁻⁹. For example, 10 MB × 1×10⁻⁹ = 1×10⁻⁸ PB.

How many megabytes are in one petabyte?

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

What is 10 megabytes in petabytes?

10 MB = 1×10⁻⁸ PB.

Is this MB to PB 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.
