Convert Terabytes to Gigabytes
1 terabyte is 1,000 GB. One terabyte is exactly 1000 gigabytes.
One terabyte is 1000 gigabytes. To convert terabytes to gigabytes, multiply by 1000; to go the other way, divide by 1000 or multiply by 0.001. The factor is exact rather than rounded: it follows from IEC 80000-13. Exactly one trillion bytes, or 1,000 gigabytes.
