Convert Megabits to Petabytes (Mbit to PB)
1 megabit (Mbit) = 1.25 × 10⁻¹⁰ petabytes (PB). 1 PB = 8000000000 Mbit. Example: 15 Mbit = 15 × 1.25 × 10⁻¹⁰ = 1.875 × 10⁻⁹ PB.

How to Convert Megabit to Petabyte
- 1 Mbit = 1.25 × 10⁻¹⁰ PB
- 1 PB = 8000000000 Mbit
- Example: convert 15 Mbit to PB: 15 Mbit = 15 × 1.25 × 10⁻¹⁰ PB = 1.875 × 10⁻⁹ PB
Formula
PB = Mbit ÷ 8000000000
Derivation from SI units:
- 1 Mbit = 10⁶ bits.
- 1 PB = 10¹⁵ bytes = 1000 TB.
- 1 Mbit = 1000000 bit ÷ 8 × 10¹⁵ bit per PB = 1.25 × 10⁻¹⁰ PB
Both units are defined exactly, so the factor is exact. Megabit definition: megabit; Petabyte definition: petabyte.
Worked examples
- A reading of 16 Mbit converts to 2 × 10⁻⁹ PB.
16 Mbit × 1.25 × 10⁻¹⁰ = 2 × 10⁻⁹ PB - A value of 128 Mbit is 1.6 × 10⁻⁸ PB.
128 Mbit × 1.25 × 10⁻¹⁰ = 1.6 × 10⁻⁸ PB

Frequently asked questions
How many petabytes are in 1 megabit?
1 Mbit = 1.25 × 10⁻¹⁰ PB.
How do I convert megabits to petabytes?
Multiply the value in Mbit by 1.25 × 10⁻¹⁰, or divide it by 8000000000. For example, 15 Mbit × 1.25 × 10⁻¹⁰ = 1.875 × 10⁻⁹ PB.
Is the Mbit to PB conversion exact?
Yes. Both units are defined exactly, and 1 Mbit is exactly 1.25 × 10⁻¹⁰ PB.
