Convert Gigabytes to Terabytes
1 gigabyte is 0.001 TB. One gigabyte is exactly 0.001 terabytes.
One gigabyte is 0.001 terabytes. To convert gigabytes to terabytes, multiply by 0.001; to go the other way, divide by 0.001 or multiply by 1000. The factor is exact rather than rounded: it follows from IEC 80000-13. Exactly one billion bytes.
