A gigabyte (GB) is a unit of digital storage equal to 1,024 megabytes (MB) or approximately 1 billion bytes. It is a standard measurement used across operating systems, storage devices, and cloud platforms to represent capacity and file size.
Gigabytes are commonly used to describe the size of applications, operating systems, high-resolution media, and storage space. For example, a 4K movie can be 10–20 GB, and smartphones today often come with 64 GB to 512 GB of internal storage.
In both hardware and networking, gigabytes serve as a reference point for system requirements, file transfers, and usage limits. Whether you're managing a cloud backup, downloading large files, or installing software, understanding gigabytes helps gauge how much space or bandwidth is needed.
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.
SI (Base 10):
Formula: Terabyte = Gigabyte ÷ "Number of Gigabytes in 1 Terabyte"
Calculation: 2 × 0.001 = 0.002 Terabyte
Binary (Base 2):
Formula: Terabyte = Gigabyte ÷ "Number of Gigabytes in 1 Terabyte"
Calculation: 2 × 0.0009765625 = 0.001953125 Terabyte
