PB to kB Converter

How to convert petabytes to kilobytes

FormulakB = PB × 1,000,000,000,000

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

A petabyte is larger than a kilobyte: one petabyte contains 1,000,000,000,000 kilobytes.

About the units

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).

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).

Frequently asked questions

How many kilobytes are in one petabyte?

There are 1,000,000,000,000 kilobytes in one petabyte, and this value is exact by definition.

How do I convert petabytes to kilobytes?

Multiply the number of petabytes by 1,000,000,000,000. For example, 10 PB × 1,000,000,000,000 = 10,000,000,000,000 kB.

How many petabytes are in one kilobyte?

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

What is 10 petabytes in kilobytes?

10 PB = 10,000,000,000,000 kB.

Is this PB to kB 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.
