Convert Bytes to Petabytes (B to PB)
1 byte (B) = 1 × 10⁻¹⁵ petabytes (PB). 1 PB = 1 × 10¹⁵ B. Example: 15 B = 15 × 1 × 10⁻¹⁵ = 1.5 × 10⁻¹⁴ PB.

How to Convert Byte to Petabyte
- 1 B = 1 × 10⁻¹⁵ PB
- 1 PB = 1 × 10¹⁵ B
- Example: convert 15 B to PB: 15 B = 15 × 1 × 10⁻¹⁵ PB = 1.5 × 10⁻¹⁴ PB
Formula
PB = B ÷ 1 × 10¹⁵
Derivation from SI units:
- 1 byte = 8 bits (an octet).
- 1 PB = 10¹⁵ bytes = 1000 TB.
- 1 B = 8 bit ÷ 8 × 10¹⁵ bit per PB = 1 × 10⁻¹⁵ PB
Both units are defined exactly, so the factor is exact. Byte definition: byte; Petabyte definition: petabyte.
Worked examples
- A reading of 512 B converts to 5.12 × 10⁻¹³ PB.
512 B × 1 × 10⁻¹⁵ = 5.12 × 10⁻¹³ PB - A value of 4096 B is 4.096 × 10⁻¹² PB.
4096 B × 1 × 10⁻¹⁵ = 4.096 × 10⁻¹² PB

Frequently asked questions
How many petabytes are in 1 byte?
1 B = 1 × 10⁻¹⁵ PB.
How do I convert bytes to petabytes?
Multiply the value in B by 1 × 10⁻¹⁵, or divide it by 1 × 10¹⁵. For example, 15 B × 1 × 10⁻¹⁵ = 1.5 × 10⁻¹⁴ PB.
Is the B to PB conversion exact?
Yes. Both units are defined exactly, and 1 B is exactly 1 × 10⁻¹⁵ PB.
