How do I convert petabytes back to bytes?

Use the reverse converter: 1 petabyte equals 1e+15 B.

Is this converter accurate?

Yes. It uses the exact SI/NIST definitions of each unit and shows up to 6 significant digits.

Decimal vs binary: KB, MB and GB use powers of 1,000 (SI), while KiB, MiB and GiB use powers of 1,024. Storage makers use decimal units; many operating systems and memory sizes use binary ones, which is why a "500 GB" drive shows less space.

About the units

Byte (B): Eight bits, the basic unit of computer storage and the size of one character in many encodings.
Petabyte (PB): 10^15 bytes in the decimal system, used in data centres and big data.
