A terabyte (TB) equals 1,024 gigabytes (GB) or about 1 trillion bytes. It's a standard unit of digital storage used to describe the capacity of hard drives, SSDs, cloud storage plans, and large-scale data systems.
Terabytes are often associated with high-capacity storage. Such as external drives, data centers, video production setups, and backup systems. A single TB can hold roughly:
As digital content grows from 4K video to big data applications, terabytes have become the new baseline for consumers and professionals managing large volumes of files. Whether you're upgrading a storage device or evaluating a hosting plan, TB is now a central unit in everyday digital infrastructure.
A petabyte (PB) is a massive unit of digital storage equal to 1,024 terabytes (TB) or over 1 quadrillion bytes. It represents a scale of data rarely encountered by individual users but increasingly common in enterprise systems, cloud storage infrastructure, scientific research, and large-scale analytics platforms.
To put it in perspective, a petabyte could store:
Organizations in sectors like cloud computing, artificial intelligence, genomics, finance, and telecommunications routinely work with petabytes of data. Whether storing backup archives or processing real-time analytics, PB-level storage marks the threshold where data becomes a true operational asset — and a challenge to manage efficiently.
SI (Base 10):
Formula: Petabyte = Terabyte ÷ "Number of Terabytes in 1 Petabyte"
Calculation: 3 × 0.001 = 0.003 Petabyte
Binary (Base 2):
Formula: Petabyte = Terabyte ÷ "Number of Terabytes in 1 Petabyte"
Calculation: 3 × 0.0009765625 = 0.0029296875 Petabyte
