A brief introduction to gigabyte, terabyte and the relationship between them are discussed in this post.


Web hosting space and disk storage terminology can be confusing, especially the words like megabytes, gigabytes, and terabytes. Many users ask us how many gigabytes in a terabyte? Or does 1 GB equal 1000 or 1024 MB? How many MB is 1 GB equal?

Probably you may also have a doubt about the above questions. Here, in this post of MiniTool, I will try my best to explain them clearly for you.

What Is Gigabyte

Before you know how many gigabytes are in a terabyte, you need to know what gigabyte and terabyte are. Gigabyte (GB) is a computer information unit consisting of 1,000,000,000 bytes in a decimal system prefixed with Giga. One gigabyte is equivalent to 1,073,741,824 bytes or 2 30 bytes in binary, 1,000,000,000 bytes or 109 bytes in a decimal system. One gigabyte in base 2 is 1,048,576 KB or 1,024 MB.

This definition is used in science, engineering, commerce and many computing areas, including hard drives, solid state drives and tape capacity, and data transfer speeds.

However, the term is also used in certain areas of computer science and information technology to represent 1 073 741 824 (1024 3 or 2 30) bytes, especially for RAM size.

The opposite side is that drive manufacturers use the standard metrics of gigabytes to define the hard disk capacity described and sold, but when it shows the capacity of a 400 GB drive through, for example, Microsoft Windows, it is reported to be 372 GB, using a binary interpretation.

Hence, gigabyte’s use may be a little ambiguous. To solve this uncertainty, the international quantity system standardizes the binary prefix, which represents a series of integer powers of 1024. 

Using these prefixes, a memory module labeled 1 GB in size has a gibibyte (1 GiB) of storage capacity.

What Is Terabyte

The terabyte (TB) is a digital information measuring unit having the prefix Tera. The correlation unit tebibyte (TiB) using the binary prefix is ​​equal to 1024 4 bytes. One terabyte is approximately 0.9095 TiB.

 Though these standardized binary prefixes are introduced, TB is still commonly used in certain computer operating systems, primarily Microsoft Windows, to represent a disk drive capacity of 1 099 511 627 776 (1024 4 or 2 40) bytes.

TB to GB Conversion

How many how many GB in a TB? How do you achieve the GB to TB conversion? In fact, there are two conversion ways about TB to GB.

  • 1 terabyte (TB) is equal to 1000 Gigabytes (GB) (decimal).
  • 1 terabyte (TB) is equal to 1024 Gigabytes (GB) (binary).

Because the size of the content varies greatly, it is not possible to specifically discuss how many videos or images or web pages can be loaded using a certain amount of data transfer.

Still, this will give you a basic idea of ​​how many images or videos you can provide via a connection.

  • Pictures or images – the size of images differs a lot from 5 gigabytes to several Assuming that each picture is 1 MB, your website can deal with 10 million pictures a month. The download of multiple photo on a single page will increase the amount of data transferred respectively.
  • Video – The one-minute HD video of a smartphone is approximately 100 MB. Similarly, these numbers are highly generalized, but if we define the video as a two-minute length for an iPhone or similar technology, your site can process 20,000 downloads per month.

As the size of the video is hundreds of times larger than the image, most websites use YouTube embedding instead of over-stressing the server through video downloads.

The Application of Gigabyte and Terabyte

Data transfer is a term with a very direct meaning. It simply refers to the move of data (content/information) from one location to another. The transmission is usually done over a public or local network.

Tip: To obtain information about data transfer rate, please take the post as a reference.

As soon as someone visits your site, data is transferred. The amount of data transfer (in bytes) required each month depends largely on the size of the content. Besides the content, you need to estimate traffic too.

Additionally, pay attention to the relationship between data transfer and bandwidth. True bandwidth is the amount of time capacity that is calculated per second, usually in megabytes per second (MBps).

However, in common usage, the data transfer limit of a managed package is often referred to as monthly bandwidth.
