How many GB are in 1 TB?


Terms like megabytes, gigabytes, and terabytes might be difficult to understand when discussing disk storage and web hosting. Many users ask us, “How many gigabytes are in a terabyte?” Do 1000 or 1024 MBs make up 1 GB? How many GB are in 1 TB? mean?

Likely, you have queries concerning the aforementioned issues as well. I will do my best to explain them to you in detail in this MiniTool post.


The term “terabyte” (TB) refers to a unit of measurement for digital information. It is now used to describe the quantity of digital data in online libraries, digital archives, and other locations. 

However, in the near future, it may also be extensively used to describe, among other things, the capacity of computer RAM. One terabyte is equal to 1000 gigabytes, or 1012 bytes.

 In contrast, 1 TB is equal to 240 or 10244 bytes, or, in terms of information technology or computer science, 1,099,511,627,776 bytes.


One of the most used measurements for digital data is the gigabyte (GB), which is 1,000,000,000 bytes. However, in the field of computer operational science, 1 GB is equivalent to 230 or 10243 bytes, or 1,073,741,824 bytes. 

GB is frequently used to denote memory size or to represent the amount of a movie, computer RAM, and other media. 

The highest amount of data that can be stored on a single-layer Blu-ray disc is equivalent to 25 GB, but the maximum amount of data that can be saved on a single-layer DVD is typically close to 4.8 GB.

How many GB are in 1 TB

In the decimal system, 1 Terabyte is equivalent to 1000 Gigabytes, making Terabyte (TB) 1000 times larger than Gigabyte (GB). Additionally, 1 Terabyte is equivalent in binary to 1024 Gigabytes.

How many MBs are in a GB?

In decimal terms, there are 1.000 MB in a GB. Additionally, a GB has 1024 MB in binary base.

In terms of decimal (SI), 1000 MB is equivalent to 1 GB. However, in binary, 1 GB is equivalent to 1.024 MB.

About 1TB

Before I show you how much 1TB is, you might need to understand the following fundamental ideas first:

Bit: The fundamental unit for storing data on computers is the bit. A bit is represented by one of the binary values, 0, or 1.

Byte: A byte is a collection of 8 binary digits. In other words, a byte is 8 bits.

Kilobyte: Kilobyte is referred to as KB. 1024 bytes make up 1 KB.

Megabyte: Megabyte is abbreviated as MB. 1024 kilobytes (KB) make up 1 megabyte (MB).

Gigabyte: A gigabyte (GB) is equal to 1024 megabytes (MB).

Terabyte: Terabyte (1 TB is equal to 1024 GB): TB stands for Terabyte.
