1E-15 petabytes
= 0.000000001 GB= 0.000001 MB
equals 1E-15 petabytesFormula: PB = B × 1e-15
Byte to Petabyte formula
PB = B × 1e-15
Convert 5 bytes to petabytes
- Start with 5 bytes.
- Multiply by the conversion factor: 5 × 1E-15 = 5E-15.
- So 5 B = 5E-15 PB.

Unit definitions
What is a byte?
The byte is eight bits, the basic addressable unit of computer memory and storage. One byte can represent a single text character in older encodings. It is the reference unit from which kilobytes, megabytes, and their binary counterparts are built.
What is a petabyte?
The petabyte (decimal) is 1000⁵ bytes, or one thousand terabytes. It is used for data-centre storage, scientific datasets, and cloud infrastructure. Large tech platforms handle many petabytes of data.
Frequently asked questions
How many petabytes are in one byte?
One byte equals 1E-15 petabytes (1 B = 1E-15 PB).
How do I convert bytes to petabytes?
Multiply the value in bytes by 1E-15. For example, 10 B × 1E-15 = 1E-14 PB.
Which is bigger — a byte or a petabyte?
A petabyte is bigger: one petabyte contains 1E15 bytes.
Is this byte to petabyte converter free?
Yes — the converter is free, works offline once loaded, and computes instantly in your browser without sending your numbers to a server.
