in maths: 1TB = 1024GB
in sql server, it's the same, AFAIK.

the only application I know that did this differently is Legato Networker, that used 1TB = 1000 1GB ...

There are 1000 Gigabytes in 1 Terabyte. There you go :)

Both 1000 GB and 1024 GB are valid answers, as it depends on what context.

Most hard drive manufactures typically use decimal based values, that is multiples of 1,000 when dealing with unformatted capacities.

When dealing with other measurements/capacities in the computer world binary numbers, or multiples of 1,024, are used.

Most operating systems will show file system capacities based on multiples of 1,024 once the drive is formatted.

Here's the answer I posted to another site a few days ago:
1 = One Byte
1000 = Kilo(bytes)
1,000,000 = Mega(bytes)
1,000,000,000 = Giga(bytes)
1,000,000,000,000 = Tera(bytes)

That's the SIMPLE answer. The TECHNICALLY ACCURATE answer is that the computers refer to things in powers of 2. 2 to the power of 10 = Kilobyte (TECHNICALLY 1024 Bytes, not 1000).

So a megabyte would be 2 to the power of 20 - TECHNICALLY 1,048,576 bytes, not 1,000,000.

To simplify - to the computer:
Kilobyte = 1024 bytes, not 1000 (2^10)
Megabyte = 1,048,576 bytes, not 1,000,000 (2^20)
Gigabyte = 1,073,741,824 bytes, not 1,000,000,000 (2^30)
Terabyte = 1,099,511,627,776 bytes, not 1,000,000,000,000 (2^40)
