# Bytes to petabytes

**1 byte in petabytes: 1 B = 1 × 10^-15 PB**

PB = B × 1 × 10^-15

To convert bytes to petabytes, multiply by 1 × 10^-15. The table below gives the values people look up most often, and the converter works for any number.

## How the conversion works

The relationship is PB = B × 1 × 10^-15. Both units measure data, so the conversion is a fixed factor that never changes.

## Common questions

### How many petabytes are in one byte?

One byte equals 1 × 10^-15 petabytes. PB = B × 1 × 10^-15.

### How do you convert bytes to petabytes?

Use PB = B × 1 × 10^-15. So 10 B is 1 × 10^-14 PB.

### How many bytes are in one petabyte?

One petabyte equals 1 × 10^15 bytes, which is the reverse of the conversion above.
