How Many Terabytes in a Petabyte?

Quick Answer

There are 1,000 terabytes in a petabyte (PB) using the SI standard, or 1,024 tebibytes in a pebibyte (PiB) using the binary standard.

1 PB = 1,000 TB (SI) or 1 PiB = 1,024 TiB (binary)

Understanding the Conversion

In the SI (decimal) standard, one petabyte (PB) equals exactly 1,000 terabytes. In the binary standard, one pebibyte (PiB) equals 1,024 tebibytes (TiB). Petabytes are used to measure massive data stores like those operated by cloud providers, streaming services, and research institutions.

Formula

1 PB = 1,000 TB (SI) or 1 PiB = 1,024 TiB (binary)
