How many GB are in one 2TB?

To be clear on the matter, 1TB, that is one Terabyte, is equal to 1,000,097,181,696 Bytes. 1GB, that is one Gigabyte, is equal to 1073741823 Bytes. When you divide the number of bytes in 1TB by the number of bytes in one GB, the answer is 931.413GB so doubling this answer, i.e. multiply by 2, one gets 1862.826GB in a 2TB HDD, and not 2048.
