Petabytes to Bytes Converter
1 petabyte (PB) equals 1 × 1015 bytes (B).
Quick answer
- 1 petabyte = 1 × 1015 bytes
- 1 byte = 1 × 10-15 petabytes
- Formula: B = PB × 1 × 1015
1 petabyte = 1 × 1015 bytes
How to convert petabytes to bytes
B = PB × 1 × 1015
To convert petabytes to bytes, multiply the number of petabytes by 1 × 1015.
Example: 18 PB to B
- Start with the value in petabytes: 18 PB.
- Multiply by 1 × 1015: 18 × 1 × 1015 = 1.8 × 1016.
- Result: 18 petabytes = 1.8 × 1016 bytes.
Going the other way, 1 byte = 1 × 10-15 petabytes, so to convert bytes back to petabytes you divide by the same number. See bytes to petabytes.
