Bits to PB Converter

How to convert bits to petabytes

FormulaPB = b × 1.25×10⁻¹⁶

Multiply the value in bits by 1.25×10⁻¹⁶. To go the other way, multiply by 8×10¹⁵ (or divide by 1.25×10⁻¹⁶).

A bit is smaller than a petabyte: it takes 8×10¹⁵ bits to make one petabyte.

About the units

Bit (b)

A single binary digit, 0 or 1.

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 bit?

There are 1.25×10⁻¹⁶ petabytes in one bit, and this value is exact by definition.

How do I convert bits to petabytes?

Multiply the number of bits by 1.25×10⁻¹⁶. For example, 10 b × 1.25×10⁻¹⁶ = 1.25×10⁻¹⁵ PB.

How many bits are in one petabyte?

One petabyte equals 8×10¹⁵ bits. That is the reverse factor, 1 ÷ 1.25×10⁻¹⁶.

What is 10 bits in petabytes?

10 b = 1.25×10⁻¹⁵ 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.
