Terabyte to Gigabyte Converter

Relationship Between Terabytes and Gigabytes

The conversion between terabytes and gigabytes is based on the binary system where 1 terabyte equals 1,024 gigabytes.

1 TB = 1,024 GB

Therefore,

1 GB = 1/1,024 TB = 0.0009765625 TB

To convert terabytes to gigabytes, we multiply the value in terabytes by 1,024.

For example, 1 TB equals 1,024 GB, and 2 TB equals 2,048 GB.

Terabyte

What is a Terabyte (TB)?

A terabyte (symbol: TB) is a unit of digital information storage equal to 1,099,511,627,776 bytes (1,024 gigabytes) in the binary system. It represents an enormous amount of data and is used to measure large-scale storage systems, enterprise servers, and modern consumer storage devices.

Origin and Development

The term 'terabyte' derives from the prefix 'tera-' meaning one trillion in the decimal system. In the binary system used by computers, 1 TB equals 1,024⁴ bytes. Terabytes became common in consumer technology in the 2000s as storage technology advanced and data-intensive applications like high-definition video, gaming, and cloud computing became widespread.

Current Use and Real-World Examples

Terabytes are now the standard unit for measuring storage capacity in modern hard drives, solid-state drives, and cloud storage services. A typical consumer laptop or desktop computer today comes with storage ranging from 256 GB to 2 TB or more. Enterprise data centers and servers often use storage measured in petabytes (thousands of terabytes). To put it in perspective: 1 TB can store approximately 250,000 photos, 500 hours of HD video, or 6.5 million document pages.

Gigabyte

What is a Gigabyte (GB)?

A gigabyte (symbol: GB) is a unit of digital information storage equal to 1,073,741,824 bytes (1,024 megabytes) in the binary system. It is widely used to measure storage capacity in hard drives, solid-state drives, memory cards, and RAM.

Origin

The term 'gigabyte' comes from the prefix 'giga-' meaning one billion in the decimal system. In computing, 1 GB equals 1,024³ bytes (1,073,741,824 bytes) due to the binary system. The IEC introduced the term 'gibibyte' (GiB) to distinguish binary gigabytes from decimal gigabytes, though 'gigabyte' remains more commonly used.

Current Use

Gigabytes are the standard unit for measuring storage capacity in personal computers, smartphones, tablets, and external storage devices. They are commonly used to describe hard drive capacities, RAM sizes, data plans for mobile networks, and file sizes for videos, software applications, and large document collections. Most consumer storage devices today range from several gigabytes to several terabytes.
