Digital storage uses binary (IEC) units throughout: 1 KB = 1,024 bytes, 1 MB = 1,024 KB = 1,048,576 bytes, 1 GB = 1,024 MB. Decimal-based variants (1 GB = 1,000,000,000 bytes) are not used here.

About Terabytes and Petabytes

Terabytes (TB): About one trillion bytes; modern hard drives and SSDs reach into the terabyte range. Common uses: Hard drive capacity, server storage, backup systems, and large dataset sizes.

Petabytes (PB): About one quadrillion bytes; large-scale enterprise and cloud storage. Common uses: Cloud storage at scale (data centers), large research datasets (CERN, genomics), and major media archives.

How the conversion works

Digital storage uses binary (IEC) units throughout: 1 KB = 1,024 bytes, 1 MB = 1,024 KB = 1,048,576 bytes, 1 GB = 1,024 MB. Decimal-based variants (1 GB = 1,000,000,000 bytes) are not used here.

The exact relationship is petabytes = terabytes × 0.0009765625, which the calculator at the top of this page applies in both directions. Type into either field and the other updates immediately.

When this conversion matters

Converting between terabytes and petabytes comes up wherever digital storage measurements move between systems — from one country's conventions to another's, from a scientific reference to a practical specification, or from one industry's working unit to another's.
