Convert Megabytes to Petabytes (MB to PB)
1 megabyte (MB) = 1 × 10⁻⁹ petabytes (PB). 1 PB = 1000000000 MB. Example: 15 MB = 15 × 1 × 10⁻⁹ = 1.5 × 10⁻⁸ PB.

How to Convert Megabyte to Petabyte
- 1 MB = 1 × 10⁻⁹ PB
- 1 PB = 1000000000 MB
- Example: convert 15 MB to PB: 15 MB = 15 × 1 × 10⁻⁹ PB = 1.5 × 10⁻⁸ PB
Formula
PB = MB ÷ 1000000000
Derivation from SI units:
- 1 MB = 10⁶ bytes = 8 × 10⁶ bits (decimal, SI).
- 1 PB = 10¹⁵ bytes = 1000 TB.
- 1 MB = 8000000 bit ÷ 8 × 10¹⁵ bit per PB = 1 × 10⁻⁹ PB
Both units are defined exactly, so the factor is exact. Megabyte definition: megabyte; Petabyte definition: petabyte.
Worked examples
- A reading of 16 MB converts to 1.6 × 10⁻⁸ PB.
16 MB × 1 × 10⁻⁹ = 1.6 × 10⁻⁸ PB - A value of 128 MB is 1.28 × 10⁻⁷ PB.
128 MB × 1 × 10⁻⁹ = 1.28 × 10⁻⁷ PB

Frequently asked questions
How many petabytes are in 1 megabyte?
1 MB = 1 × 10⁻⁹ PB.
How do I convert megabytes to petabytes?
Multiply the value in MB by 1 × 10⁻⁹, or divide it by 1000000000. For example, 15 MB × 1 × 10⁻⁹ = 1.5 × 10⁻⁸ PB.
Is the MB to PB conversion exact?
Yes. Both units are defined exactly, and 1 MB is exactly 1 × 10⁻⁹ PB.
