**There are 1024 gigabytes (GB) in 1 Terabyte (TB) i.e. 1, 000 GB (Gigabytes) in a Terabyte**

1 TB = 1000000000000bytes = 1012bytes = 1000gigabytes.

This is so because prefix tera in “terabyte” represents the fourth power of 1000, and means 1012 in the International System of Units (SI). Terabyte is one trillion (short scale) bytes.

Gigabyte (GB) is one of the most commonly used units of digital information which is equal to 1, 000, 000, 000 bytes. However, in computer operating science, the value of 1 GB is considered to be equal to 230 or 10243 bytes which is equal to 1, 073, 741, 824 bytes.

Terabyte (TB) is a digital information measurement unit which is going to be extensively used in the nearest future for measuring the size of computer RAM, etc. 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.

Not to get confused, there are actually two different number systems which are used to express units of storage capacity, they are

- binary – Where a kilobyte is equal to 1024 bytes
- decimal, where a kiloybyte is equal to 1000 bytes

In the other hand, the tebibyte (TiB) used by geeks, is a binary prefix equal to 10244 bytes. One terabyte is about 0.9095 TiB. Despite the introduction of these standardized binary prefixes

**Calculate how many Gigabyte in a Terabyte in SI**

1 Gigabyte = 1000^{3} bytes

We know that 1TB = 1000^{4} bytes,

so 1 byte = 1000^{-4} TB

putting 1 byte in gigabyte equation;

1 Gigabyte = 1000^{3} * 1000^{-4} TB

1 Gigabyte = 1000^{-1} TB 1 Gigabyte = 0.001 Terabytes

**Calculate how many Gigabyte in a Terabyte in base 2**

1 Gigabyte = 2^{30} bytes 1

Gigabyte = 1024^{3}

bytes 1 byte = 1024^{-4} TB

1 Gigabyte = 1024^{3} * 1024^{-4} TB

1 Gigabyte = 1024^{-1} TB

1 Gigabyte = 2^{-10} Terabytes

1 Gigabyte = 0.0009765625 Terabytes
