Convert Petabytes to Bits (PB to bit)
1 petabyte (PB) = 8 × 10¹⁵ bits (bit). 1 bit = 1.25 × 10⁻¹⁶ PB. Example: 15 PB = 15 × 8 × 10¹⁵ = 1.2 × 10¹⁷ bit.

How to Convert Petabyte to Bit
- 1 PB = 8 × 10¹⁵ bit
- 1 bit = 1.25 × 10⁻¹⁶ PB
- Example: convert 15 PB to bit: 15 PB = 15 × 8 × 10¹⁵ bit = 1.2 × 10¹⁷ bit
Formula
bit = PB × 8 × 10¹⁵
Derivation from SI units:
- 1 PB = 10¹⁵ bytes = 1000 TB.
- The basic unit of information: one binary digit, 0 or 1.
Both units are defined exactly, so the factor is exact. Petabyte definition: petabyte; Bit definition: bit.
Worked examples
- A reading of 1 PB converts to 8 × 10¹⁵ bit.
1 PB × 8 × 10¹⁵ = 8 × 10¹⁵ bit - A value of 10 PB is 8 × 10¹⁶ bit.
10 PB × 8 × 10¹⁵ = 8 × 10¹⁶ bit

Where it's used
Petabytes are used for data centres and cloud providers, while bits appear in network speeds (bits per second). Both measure amount of digital information, so the conversion is a fixed factor.

Frequently asked questions
How many bits are in 1 petabyte?
1 PB = 8 × 10¹⁵ bit.
How do I convert petabytes to bits?
Multiply the value in PB by 8 × 10¹⁵. For example, 15 PB × 8 × 10¹⁵ = 1.2 × 10¹⁷ bit.
Is the PB to bit conversion exact?
Yes. Both units are defined exactly, and 1 PB is exactly 8 × 10¹⁵ bit.
