## How the conversion works

The relationship is PB = MB × 1 × 10^-9. Both units measure data, so the conversion is a fixed factor that never changes.

> Megabyte: Decimal: 1,000,000 bytes.

## Common questions

### How many petabytes are in one megabyte?

One megabyte equals 1 × 10^-9 petabytes. PB = MB × 1 × 10^-9.

### How do you convert megabytes to petabytes?

Use PB = MB × 1 × 10^-9. So 10 MB is 1 × 10^-8 PB.

### How many megabytes are in one petabyte?

One petabyte equals 1,000,000,000 megabytes, which is the reverse of the conversion above.

### Is there more than one kind of megabyte?

Decimal: 1,000,000 bytes.
