1,000 terabytes

= 1,000,000 GB= 1E15 B

equals 1,000 terabytes

Formula: TB = PB × 1000

Petabyte to Terabyte formula

TB = PB × 1000

Convert 5 petabytes to terabytes

  1. Start with 5 petabytes.
  2. Multiply by the conversion factor: 5 × 1,000 = 5,000.
  3. So 5 PB = 5,000 TB.

Unit definitions

What is a petabyte?

The petabyte (decimal) is 1000⁵ bytes, or one thousand terabytes. It is used for data-centre storage, scientific datasets, and cloud infrastructure. Large tech platforms handle many petabytes of data.

What is a terabyte?

The terabyte (decimal) is one trillion bytes (1000⁴) under the SI convention. Modern hard drives and large media libraries are measured in terabytes. It differs from the binary tebibyte (1024⁴ bytes).

Frequently asked questions

How many terabytes are in one petabyte?

One petabyte equals 1,000 terabytes (1 PB = 1,000 TB).

How do I convert petabytes to terabytes?

Multiply the value in petabytes by 1,000. For example, 10 PB × 1,000 = 10,000 TB.

Which is bigger — a petabyte or a terabyte?

A petabyte is bigger: one petabyte contains 1,000 terabytes.

Is this petabyte to terabyte converter free?

Yes — the converter is free, works offline once loaded, and computes instantly in your browser without sending your numbers to a server.
