How to convert petabytes to terabytes
TB = PB × 1,000Multiply the value in petabytes by 1,000. To go the other way, multiply by 0.001 (or divide by 1,000).
A petabyte is larger than a terabyte: one petabyte contains 1,000 terabytes.

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).
Terabyte (TB)
10¹² bytes. Hard drives and SSDs are marketed in decimal terabytes. One terabyte equals 8,000,000,000,000 bits (b).
Frequently asked questions
How many terabytes are in one petabyte?
There are 1,000 terabytes in one petabyte, and this value is exact by definition.
How do I convert petabytes to terabytes?
Multiply the number of petabytes by 1,000. For example, 10 PB × 1,000 = 10,000 TB.
How many petabytes are in one terabyte?
One terabyte equals 0.001 petabytes. That is the reverse factor, 1 ÷ 1,000.
What is 10 petabytes in terabytes?
10 PB = 10,000 TB.
Is this PB to TB 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.
