UnitConTerabytes to Gigabytes Converter
Convert terabytes to gigabytes for server planning, NAS (network-attached storage) sizing, and comparing large drive capacities. Enterprise and consumer storage products increasingly use terabyte-scale capacities.
Formula
Multiply terabytes by 1000 to get gigabytes (decimal). To reverse, divide gigabytes by 1000 to get terabytes.

About these units
Terabyte
The terabyte (10¹² bytes) became a commercial reality in the mid-2000s as hard drives crossed the terabyte threshold. Enterprise SAN (storage area network) systems are now routinely measured in petabytes.
Gigabyte
The gigabyte scale dominated consumer storage from the 1990s through the 2010s. USB drives, SSDs, and cloud storage tiers are still commonly specified in gigabytes.
Frequently asked questions
2 × 1000 = 2000 GB.
1000 ÷ 4 = 250 movies (approximate).
1 TB (decimal) = 1,000,000,000,000 bytes; 1 TiB (binary) = 1,099,511,627,776 bytes. A 1 TB hard drive contains approximately 0.909 TiB.
