Convert Bits to Petabytes (bit to PB)
1 bit = 1.25 × 10⁻¹⁶ petabytes (PB). 1 PB = 8 × 10¹⁵ bit. Example: 15 bit = 15 × 1.25 × 10⁻¹⁶ = 1.875 × 10⁻¹⁵ PB.

How to Convert Bit to Petabyte
- 1 bit = 1.25 × 10⁻¹⁶ PB
- 1 PB = 8 × 10¹⁵ bit
- Example: convert 15 bit to PB: 15 bit = 15 × 1.25 × 10⁻¹⁶ PB = 1.875 × 10⁻¹⁵ PB
Formula
PB = bit ÷ 8 × 10¹⁵
Derivation from SI units:
- The basic unit of information: one binary digit, 0 or 1.
- 1 PB = 10¹⁵ bytes = 1000 TB.
Both units are defined exactly, so the factor is exact. Bit definition: bit; Petabyte definition: petabyte.
Worked examples
- A reading of 16 bit converts to 2 × 10⁻¹⁵ PB.
16 bit × 1.25 × 10⁻¹⁶ = 2 × 10⁻¹⁵ PB - A value of 128 bit is 1.6 × 10⁻¹⁴ PB.
128 bit × 1.25 × 10⁻¹⁶ = 1.6 × 10⁻¹⁴ PB

Frequently asked questions
How many petabytes are in 1 bit?
1 bit = 1.25 × 10⁻¹⁶ PB.
How do I convert bits to petabytes?
Multiply the value in bit by 1.25 × 10⁻¹⁶, or divide it by 8 × 10¹⁵. For example, 15 bit × 1.25 × 10⁻¹⁶ = 1.875 × 10⁻¹⁵ PB.
Is the bit to PB conversion exact?
Yes. Both units are defined exactly, and 1 bit is exactly 1.25 × 10⁻¹⁶ PB.
