kB to PB Converter

Convert kilobytes (kB) to petabytes (PB). 1 kilobyte = 1×10⁻¹² petabytes (exact)

1 kilobyte = 1×10⁻¹² petabytes

How to convert kilobytes to petabytes

FormulaPB = kB × 1×10⁻¹²

Multiply the value in kilobytes by 1×10⁻¹². To go the other way, multiply by 1,000,000,000,000 (or divide by 1×10⁻¹²).

A kilobyte is smaller than a petabyte: it takes 1,000,000,000,000 kilobytes to make one petabyte.

About the units

Kilobyte (kB)

1,000 bytes (decimal). Some software still uses “KB” for 1,024 bytes; that is properly a kibibyte (KiB). One kilobyte equals 8,000 bits (b).

Petabyte (PB)

The petabyte (PB) is a unit of data storage in the International System of Units (SI). One petabyte equals 8×10¹⁵ bits (b).

Frequently asked questions

How many petabytes are in one kilobyte?

There are 1×10⁻¹² petabytes in one kilobyte, and this value is exact by definition.

How do I convert kilobytes to petabytes?

Multiply the number of kilobytes by 1×10⁻¹². For example, 10 kB × 1×10⁻¹² = 1×10⁻¹¹ PB.

How many kilobytes are in one petabyte?

One petabyte equals 1,000,000,000,000 kilobytes. That is the reverse factor, 1 ÷ 1×10⁻¹².

What is 10 kilobytes in petabytes?

10 kB = 1×10⁻¹¹ PB.

Is this kB to PB converter accurate?

Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
