How to Convert Petabytes to Megabits
To convert petabytes to megabits, multiply by 8 then adjust for scale. This converts byte-based storage measurements to bit-based units. See also: how many Petabytes in a Mb.
PB is a byte-based unit used for measuring file sizes and storage capacity. You might also need: how many Mib in Petabytes.
Mb is a bit-based unit—multiply bytes by 8 to get bits. Learn more: Pebibytes to Mb.
1 PB = 8,000,000,000 Mb (using SI decimal standard) — which means there are 8,000,000,000megabits in every petabyte.
PB to Mb Conversion Formula
// Convert PB to Mb
Mb = PB × 8,000,000,000
// Reverse: Convert Mb to PB
PB = Mb × 1.250000e-10
PB to Mb Conversion Examples
100 PB = 800,000,000,000 Mb
256 PB = 2,048,000,000,000 Mb
500 PB = 4,000,000,000,000 Mb
1,000 PB = 8,000,000,000,000 Mb

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. Learn more: convert Zib to Tebibytes.
The petabyte is a SI decimal unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. See also: Petabytes Per Second to ZiB/s calculator.
Common uses: Data centers, cloud storage providers, scientific research, enterprise archives Use our PB to Exbibytes converter.
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 Megabit?
A megabit is 1,000 kilobits or 1,000,000 bits. Standard unit for internet connection speeds. Try the Yobibytes to Megabits conversion.
The megabit is a SI decimal bit unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Try the convert Exabytes to Bytes.
Common uses: Internet speeds (Mbps), video streaming bitrates, network bandwidth Check out our Yobibits Per Second to Exabits Per Second calculator.
1 Mb = 1 × 10⁶ bits = 125,000 bytes.
The megabit can be abbreviated as Mb; for example, 1 megabit can be written as 1 Mb.
