Convert Kilobytes to Petabytes (kB to PB)
1 kilobyte (kB) = 1 × 10⁻¹² petabytes (PB). 1 PB = 1000000000000 kB. Example: 15 kB = 15 × 1 × 10⁻¹² = 1.5 × 10⁻¹¹ PB.

How to Convert Kilobyte to Petabyte
- 1 kB = 1 × 10⁻¹² PB
- 1 PB = 1000000000000 kB
- Example: convert 15 kB to PB: 15 kB = 15 × 1 × 10⁻¹² PB = 1.5 × 10⁻¹¹ PB
Formula
PB = kB ÷ 1000000000000
Derivation from SI units:
- 1 kB = 1000 bytes = 8000 bits (decimal, SI).
- 1 PB = 10¹⁵ bytes = 1000 TB.
- 1 kB = 8000 bit ÷ 8 × 10¹⁵ bit per PB = 1 × 10⁻¹² PB
Both units are defined exactly, so the factor is exact. Kilobyte definition: kilobyte; Petabyte definition: petabyte.
Worked examples
- A reading of 16 kB converts to 1.6 × 10⁻¹¹ PB.
16 kB × 1 × 10⁻¹² = 1.6 × 10⁻¹¹ PB - A value of 128 kB is 1.28 × 10⁻¹⁰ PB.
128 kB × 1 × 10⁻¹² = 1.28 × 10⁻¹⁰ PB

Where it's used
Kilobytes are used for small files, emails and web pages, while petabytes appear in data centres and cloud providers. Both measure amount of digital information, so the conversion is a fixed factor.

Frequently asked questions
How many petabytes are in 1 kilobyte?
1 kB = 1 × 10⁻¹² PB.
How do I convert kilobytes to petabytes?
Multiply the value in kB by 1 × 10⁻¹², or divide it by 1000000000000. For example, 15 kB × 1 × 10⁻¹² = 1.5 × 10⁻¹¹ PB.
Is the kB to PB conversion exact?
Yes. Both units are defined exactly, and 1 kB is exactly 1 × 10⁻¹² PB.
