A** Gigabyte** **(GB) **is a unit of data or storage information that consists of 1 billion bytes in the base 10 system (aka decimal or SI).

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

### What is a Terabyte (TB)?

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

So, one Terabyte has the equivalent of:

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

Nowadays, most large organizations will use Terabytes to measure their data storage.

### How many Gigabytes are in one Terabyte?

Based on the above-mentioned conversions, there are 1,000 Gigabytes in 1 Terabyte.

In other words, a Terabyte is one thousand times bigger than a Gigabyte.

### What is the difference between a Gigabyte (GB) and Terabyte (TB)?

A** Terabyte** is a unit of digital info equal to 1000 Gigabytes under base 10 and 1024 Gigabytes under base 2.

In other words, one Terabyte is equal to 2^{10} Gigabytes under the base 2, binary system.

There are 1.07 billion bytes in one Gigabyte (officially 1,073,741,824 bytes).

One TB has roughly 1.1 billion bytes (1,099,511,627,776 bytes).

### How many bytes are in one gigabyte?

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

This is the same as 2^{30} bytes in base 2 (binary).

It is equal to 1 billion bytes or 10^{9} bytes in base 10 (the decimal or SI system).

One Gigabyte has 1,048,576 KB or 1024 MB under base 2.

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

One Terabyte has 1,024 Gigabytes in base 2.

When we multiply 1024 by 2, we get 2048.

So there are 2048 gigabytes in two terabytes.
