Frequently asked questions

How do I convert terabytes to gigabytes?

1 terabyte = 1,000 gigabytes, so multiply by 1,000. For example, 4 TB = 4,000 GB.

How many gigabytes are in one terabyte?

Why are there two answers for data sizes?

Storage makers, networks and the SI standard use powers of 1,000 (1 GB = 1,000 MB). Windows and many apps count in powers of 1,024, which are strictly gibibytes and mebibytes. That is why a 1 TB drive shows up as about 931 GB on a Windows PC.
