How to convert terabytes to gigabytes
To convert terabytes to gigabytes, multiply by 1000. For example, 2 TB × 1000 = 2000 GB. Going the other way, divide gigabytes by 1000 to get terabytes.
In binary, 1 TiB = 1024 GiB. Hard drive manufacturers use decimal while operating systems sometimes use binary, which is why a 1 TB drive shows as less than 1000 GB in Windows.
1 TB = 1000 GB = 1,000,000 MB = 1,000,000,000 KB (decimal). Terabytes are commonly used for hard drives, SSDs, and cloud storage.
