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 byte is a standard unit of digital information made up of 8 bits. It's the basic building block for representing data in computers, where a single byte can typically store one character — such as a letter, number, or symbol.
Bytes are the foundation for measuring file size and storage capacity. Whether you're looking at the size of a text file or the storage available on a USB drive, the number is usually expressed in bytes or its larger multiples: kilobytes (KB), megabytes (MB), gigabytes (GB), and terabytes (TB).
In memory and storage systems, bytes play a critical role in data organization. Operating systems, applications, and databases are designed to read and write data in byte-sized chunks. As a result, understanding how bytes work is key to grasping how digital systems store, transfer, and manage information.
SI (Base 10):
Formula: Byte = Terabyte ÷ "Number of Terabytes in 1 Byte"
Calculation: 100 × 1000000000000 = 100000000000000 Byte
Binary (Base 2):
Formula: Byte = Terabyte ÷ "Number of Terabytes in 1 Byte"
Calculation: 100 × 1099511627776 = 109951162777600 Byte
