How many gigabytes are in a terabyte?

There are 1,000 gigabytes in a terabyte, although the figure may be 1,024 gigabytes in a terabyte, depending on the storage system. With a processor or virtual storage, the extra 24 gigabytes are included. They are not if the figures refer to disk storage.

Gigabytes are the normal storage unit in most computers, but terabytes stand to become the standard. Many people buy terabyte external hard drives to back up their computers or to simply have additional storage. Once terabytes become the standard, it is likely that petabyte hard drives will begin surfacing in stores. One petabyte equals 1,000 terabytes in disk storage.
