 # How Many Gigabytes Are in One Terabyte?

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 210 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 230 bytes in base 2 (binary).

It is equal to 1 billion bytes or 109 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.
