# 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 10^{3} GB in base 10, and 1 TB is equal to 2^{10} GB in base 2.

In SI and base 10, one terabyte is equivalent to 1000^{4} bytes or 1,000,000,000,000 bytes.

In base 2 (binary), one terabyte is equivalent to 1024^{4} bytes or 1,099,511,627,776 bytes.

In SI and base 10, 1 Gigabyte is equal to 1000^{3} 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 1024^{3} 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 1024^{4} (1,099,511,627,776) bytes. And 1 byte is 1024^{-3} GB.

When we multiply 1024^{4} and 1024^{-3} GB, we will get 1024^{1} Gigabytes. So finally we can say that 1 Terabyte is 1024 (or 2^{10}) Gigabytes.
