How to Convert Petabytes to Bits
To convert petabytes to bits, multiply by 8 then adjust for scale. This converts byte-based storage measurements to bit-based units. See also: Bits to PB calculator.
PB is a byte-based unit used for measuring file sizes and storage capacity. Check out our convert PB to Bytes.
b is a bit-based unit—multiply bytes by 8 to get bits. Learn more: Mebibytes to b.
1 PB = 8.000000000000e+15 b (using SI decimal standard) — which means there are 8.000000000000e+15bits in every petabyte.
PB to b Conversion Formula
// Convert PB to b
b = PB × 8.000000000000e+15
// Reverse: Convert b to PB
PB = b × 1.250000e-16
PB to b Conversion Examples
100 PB = 8.000000000000e+17 b
256 PB = 2.048000000000e+18 b
500 PB = 4.000000000000e+18 b
1,000 PB = 8.000000000000e+18 b
2,048 PB = 1.638400000000e+19 b
What Is a Petabyte?
A petabyte is 1,000 terabytes or 1,000,000,000,000,000 bytes. Used for large-scale enterprise and cloud storage. See also: how many B in Kibibits.
The petabyte is a SI decimal unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Learn more: how many Exabits Per Second in a Kibps.
Common uses: Data centers, cloud storage providers, scientific research, enterprise archives See also: calculate PB to Yib.
1 PB = 8 × 10¹⁵ bits = 1 × 10¹⁵ bytes.
The petabyte can be abbreviated as PB; for example, 1 petabyte can be written as 1 PB.
What Is a Bit?
The smallest unit of digital information, representing a single binary value of 0 or 1. Related: Zib to b conversion rate.
The bit is a fundamental unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Use our converting Tebibits to Kibibytes.

💡 Storage Engineer Tip
Multiply bytes by 8 to get bits. A 10 MB file requires 80 Mb of bandwidth—essential when calculating transfer times over network links.
