A bit is the smallest unit of digital information, short for "binary digit." It represents a value of either 0 or 1, forming the foundation of all data in computing systems. Bits are the building blocks of binary code, which powers everything from simple text files to complex artificial intelligence models.
In everyday use, file sizes and storage are rarely measured in bits. Instead, bits are grouped into larger units such as bytes, kilobytes, megabytes, and beyond. Even so, the bit remains a fundamental concept. It's the starting point of all digital information, forming the base upon which every file, app, or system is built. Understanding bits helps make sense of how digital devices store and process data at their core.
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 = Bit ÷ "Number of Bits in 1 Terabyte"
Calculation: 100 × 1.25E-13 = 1.25E-11 Terabyte
Binary (Base 2):
Formula: Terabyte = Bit ÷ "Number of Bits in 1 Terabyte"
Calculation: 100 × 1.1368683772162E-13 = 1.1368683772162E-11 Terabyte
