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 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 = Gigabyte ÷ "Number of Gigabytes in 1 Petabyte"
Calculation: 100 × 1.0E-6 = 0.0001 Petabyte
Binary (Base 2):
Formula: Petabyte = Gigabyte ÷ "Number of Gigabytes in 1 Petabyte"
Calculation: 100 × 9.5367431640625E-7 = 9.5367431640625E-5 Petabyte
