# How Many GB in a TB? How many GB in a TB? In this article, we’ll discuss about this conversion but we need to understand some key terms first before getting started.

## What is Gigabyte?

Gigabyte (GB) is basically a computer information unit that consists of 1,000,000,000 bytes in a decimal system prefixed with Giga. One gigabyte is equivalent to 1,073,741,824 bytes or 230 bytes in binary, 1,000,000,000 bytes or 109 bytes in a decimal system. 1 Gigabyte in base 2 is 1,048,576 KB or 1,024 MB.

It is used in science, engineering, commerce and many computing fields, including hard drives, solid state drives and tape capacity, and data transfer speeds, is also used in certain areas of computer science and information technology to represent, especially for its RAM size.

## What is Terabytes?

Terabyte (TB) is a digital information measuring unit which is going to be extensively used for measuring the size of computer RAM, etc., but for now it is being used for measuring the amount of digital information in online libraries, digital archives, and so on.

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 10244 bytes. One terabyte is approximately 0.9095 TiB. TB is commonly used in certain computer operating systems, primarily Microsoft Windows, to represent a disk drive capacity of 1 099 511 627 776 (10244 or 240) bytes.

According to the binary convention 1024 gigabytes equal one terabyte, while according to the SI standard 1000 gigabytes equal 1 terabyte.

1 Terabyte is equal to 1000 Gigabytes, or 1012 bytes. However, in terms of information technology or computer science, 1 TB is 240 or 10244 bytes, which is equal to 1,099,511,627,776 bytes.

## How many gigabyte in a terabyte?

We can find it by using two methods: By using converter or by using mathematical formula.

### By Using Converter

• In this method you just need to enter the value that you want to convert in the TB field as we can see in the above image.
• In the next step, you’ll get your value in GB (as per your requirement).

### By Using Mathematical Formula

GB = TB * 1024

Let’s have a look at the example,

Ex. – How to convert 8 Terabytes to Gigabytes using the formula?

8 TB = (8 × 1024) = 8192 GB

## Is 1000 GB the same as 1 TB?

When we take an example, and use the decimal standard, 1 TB is equal to 1,000 gigabytes (GBs), while when the binary standard is used, 1 TB is equal to 1,024 GB.

## What is bigger 1 TB or 100 GB?

A Terabyte is bigger than a Gigabyte. Since, a terabyte is equal to 1,024 gigabytes, which itself is equal to 1,024 megabytes (MB), while a megabyte is equivalent to 1,024 kilobytes. All storage measuring units – kilobyte, megabyte, terabyte, gigabyte, petabyte, exabyte and so on are multiples of a byte.
