View the megabit data unit pageHow 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.
PB is a byte-based unit used for measuring file sizes and storage capacity.
Mb is a bit-based unit—multiply bytes by 8 to get bits. Related: Petabytes to Kilobits.
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 rate: 1 petabyte equals 8,000,000,000megabits — the standard petabyte to megabit data storage conversion used by this calculator.

PB to Mb Conversion Formula
Here's the exact PB to Mb formula in copy-paste-ready form — multiply by 8,000,000,000 to go from petabytes to megabits, or by 1.250000e-10 to reverse it — followed by a quick-reference chart of the same conversion.
// Convert PB to Mb
Mb = PB × 8,000,000,000
// Reverse: Convert Mb to PB
PB = Mb × 1.250000e-10
