Convert Petabytes to Megabits (PB to Mbit)
1 petabyte (PB) = 8000000000 megabits (Mbit). 1 Mbit = 1.25 × 10⁻¹⁰ PB. Example: 15 PB = 15 × 8000000000 = 120000000000 Mbit.

How to Convert Petabyte to Megabit
- 1 PB = 8000000000 Mbit
- 1 Mbit = 1.25 × 10⁻¹⁰ PB
- Example: convert 15 PB to Mbit: 15 PB = 15 × 8000000000 Mbit = 120000000000 Mbit
Formula
Mbit = PB × 8000000000
Derivation from SI units:
- 1 PB = 10¹⁵ bytes = 1000 TB.
- 1 Mbit = 10⁶ bits.
- 1 PB = 8 × 10¹⁵ bit ÷ 1000000 bit per Mbit = 8000000000 Mbit
Both units are defined exactly, so the factor is exact. Petabyte definition: petabyte; Megabit definition: megabit.
Worked examples
- A reading of 1 PB converts to 8000000000 Mbit.
1 PB × 8000000000 = 8000000000 Mbit - A value of 10 PB is 80000000000 Mbit.
10 PB × 8000000000 = 80000000000 Mbit
