## How the conversion works

The relationship is TB = PB × 1,000. Both units measure data, so the conversion is a fixed factor that never changes.

## Common questions

### How many terabytes are in one petabyte?

One petabyte equals 1,000 terabytes. TB = PB × 1,000.

### How do you convert petabytes to terabytes?

Use TB = PB × 1,000. So 10 PB is 10,000 TB.

### How many petabytes are in one terabyte?

One terabyte equals 0.001 petabytes, which is the reverse of the conversion above.
