Bytes to PB Converter

How to convert bytes to petabytes

FormulaPB = B × 1×10⁻¹⁵

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

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

About the units

Byte (B)

Eight bits; the basic addressable unit of memory. One byte equals 8 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 byte?

There are 1×10⁻¹⁵ petabytes in one byte, and this value is exact by definition.

How do I convert bytes to petabytes?

Multiply the number of bytes by 1×10⁻¹⁵. For example, 10 B × 1×10⁻¹⁵ = 1×10⁻¹⁴ PB.

How many bytes are in one petabyte?

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

What is 10 bytes in petabytes?

10 B = 1×10⁻¹⁴ PB.

Is this B 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.
