Terabytes (TB) to Petabytes (PB) Conversion
Terabytes
The terabyte (TB) is a unit of digital information equal to 1,000,000,000,000 bytes (10¹² bytes) in SI decimal, or 1,099,511,627,776 bytes in binary convention. Consumer hard drives and SSDs are now commonly sold in 1–4 TB capacities. The entire text collection of the US Library of Congress is estimated at approximately 20 TB. In data centres, individual server storage arrays routinely exceed hundreds of terabytes.
Petabytes
The petabyte (PB) is a unit of digital information equal to 10¹⁵ bytes (1,000 terabytes). At the petabyte scale, measurement enters the realm of enterprise data centres and scientific research archives. The Large Hadron Collider at CERN generates approximately 15 petabytes of data per year. Major social media platforms and cloud providers store and process data in the exabyte range, making petabytes the operational scale of big data analytics.
