Convert PB to bits
Petabytes to bits. Enter a value to convert, or use the PB to bits chart further down the page.
1 petabyte equals 9.007199255e15 bits. Going the other way, 1 bit = 1.110223025e-16 petabytes.
Note. This converter uses the binary convention: 1 KB = 1024 bytes, 1 MB = 1024 KB, 1 GB = 1024 MB. That is what Windows, macOS and Linux report. Storage manufacturers instead use decimal SI units where 1 GB = 1,000,000,000 bytes, which is why a “1 TB” drive shows up as about 931 GB.
How to convert PB to bits
To convert petabytes to bits, multiply the petabyte value by 9.007199255e15. You can also divide by 1.110223025e-16 to get the same answer.
