The relationship between gigabytes (GB) and terabytes (TB) is based on the binary system used in computing. Specifically, one terabyte is equal to 1024 gigabytes. This is because in binary, each unit of measurement is based on powers of two.

Here’s how it breaks down:

1 TB can be calculated as:

- 1 TB = 2^10 GB = 1024 GB.

This only holds true in the context of binary measurement. The definition stems from the fact that computers operate in binary, where every step up in capacity is a multiplication by 2 (rather than the decimal system's multiplication by 10).

As a result, this understanding confirms why the statement "1 TB equals 1024 GB" is accurate. It aligns with the underlying principles of data storage and computing, directly reflecting how these units are defined and used in the industry.
