# How Many Gigabytes Are in One Terabyte?

### How many Gigabytes are in one Terabyte?

A Gigabyte (GB) is a unit of computer information consisting of 1 billion bytes in the base 10 (decimal / SI) system.

A Terabyte (TB) consists of 1 trillion bytes in the decimal system.

Therefore, there are 1,000 Gigabytes in 1 Terabyte. Put another way, a Terabyte is one thousand times bigger than a Gigabyte.

### What is the difference between a Gigabyte and Terabyte?

As mentioned above, a Terabyte is a unit of digital information equal to 1,024 Gigabytes under base 2.

Put another way, one Terabyte is equal to 210 Gigabytes under the binary system.

There are 1.07 billion bytes in one GB (1,073,741,824 bytes). One TB has approximately 1.1 billion bytes (1,099,511,627,776 bytes).

### What is a Terabyte (TB)?

A Terabyte is a unit of computer storage information that consists of 1,099,511,627,776 bytes under base 2 (binary system).

This means one Terabyte has:

• 1024 Gigabytes (under base)
• 1,048,576 (1024*1024) Megabytes, or
• just under 0.001 Petabytes

Nowadays, most companies use Terabytes to measure their data storage.

### How many bytes are in one gigabyte?

One Gigabyte is equal to roughly 1.07 billion bytes (1,073,741,824 bytes, to be exact).

This is equal to 230 bytes in base 2 (binary).

It is equal to 1 billion bytes or 109 bytes in base 10 (the decimal system).

One Gigabyte has 1,048,576 KB or 1,024 MB in base 2.

### How many Gigabytes (GBs) are in 2 Terabytes (TB)?

One Terabyte has 1,024 Gigabytes in base 2.

So when we multiply 1024 by 2, we get 2048.

Accordingly, there are 2048 gigabytes in two terabytes.

We have another article where we convert Terabytes to Gigabytes with a table to help convert various TB and GB amounts.
