PB to Bytes Converter

Convert petabytes (PB) to bytes (B). 1 petabyte = 1×10¹⁵ bytes (exact)

1 petabyte = 1×10¹⁵ bytes

How to convert petabytes to bytes

FormulaB = PB × 1×10¹⁵

Multiply the value in petabytes by 1×10¹⁵. To go the other way, multiply by 1×10⁻¹⁵ (or divide by 1×10¹⁵).

A petabyte is larger than a byte: one petabyte contains 1×10¹⁵ bytes.

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).

Byte (B)

Eight bits; the basic addressable unit of memory. One byte equals 8 bits (b).

Frequently asked questions

How many bytes are in one petabyte?

There are 1×10¹⁵ bytes in one petabyte, and this value is exact by definition.

How do I convert petabytes to bytes?

Multiply the number of petabytes by 1×10¹⁵. For example, 10 PB × 1×10¹⁵ = 1×10¹⁶ B.

How many petabytes are in one byte?

One byte equals 1×10⁻¹⁵ petabytes. That is the reverse factor, 1 ÷ 1×10¹⁵.

What is 10 petabytes in bytes?

10 PB = 1×10¹⁶ B.

Is this PB to B 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.
