tera-

Beyond giga-, metrically

Tera- is a metric prefix meaning one trillion (10¹²).

It appears in scientific measurements like terawatt and in computing terms like terabyte, where it indicates roughly one trillion units—though in digital storage, a terabyte is technically 2⁴⁰ bytes.

The data center stores several terabytes of information.
