# How many Gigabytes are in a Terabyte

How many Gigabytes are in a Terabyte?

One Terabyte is equal to one thousand gigabytes according to the decimal system. So, a terabyte is one thousand times bigger than a gigabyte. On the other hand, there are 1024 gigabytes in one terabyte in the binary system which computers use. We can also say that 1 TB is equal to 103 GB in base 10, and 1 TB is equal to 210 GB in base 2.

In SI and base 10, one terabyte is equivalent to 10004 bytes or 1,000,000,000,000 bytes.

In base 2 (binary), one terabyte is equivalent to 10244 bytes or 1,099,511,627,776 bytes.

In SI and base 10, 1 Gigabyte is equal to 10003 bytes. That also means there are 1,000,000,000 bytes in one gigabyte.

But if we are talking about computers language, then we must say that 1 Gigabyte is equal to 10243 bytes. That also means there are 1,073,741,824 bytes in one gigabyte.

How do you calculate terabytes to gigabytes?

We know that one terabyte is equal to 10244 (1,099,511,627,776) bytes. And 1 byte is 1024-3 GB.

When we multiply 10244 and 1024-3 GB, we will get 10241 Gigabytes. So finally we can say that 1 Terabyte is 1024 (or 210) Gigabytes.
