How to convert terabytes to gibibytes
To convert a measurement in terabytes to gibibytes, multiply the value by 931.322575. The conversion factor comes from the relationship between both units and the byte.
For example, to convert 5 TB to gibibytes: 5 × 931.322575 = 4,656.6129 GiB.
What is a terabyte?
A terabyte is 1,000,000,000,000 bytes (1,000 gigabytes) under the SI decimal convention. The binary equivalent of 1,099,511,627,776 bytes is the tebibyte (TiB). The terabyte moved from data-center jargon to the home as hard drives crossed the 1 TB mark in 2007. It is now the common unit for desktop drives and network-attached storage.
Common uses of terabytes include: Desktop hard drives and external backup drives; Network-attached storage (NAS) systems; Large media and photo libraries; Video production and archival storage.
What is a gibibyte?
A gibibyte is exactly 1,073,741,824 bytes (2^30), the binary counterpart of the gigabyte defined by the IEC. This is why a 1 GB figure and a 1 GiB figure differ by about 7%. The gibibyte resolves the most visible storage confusion: drive makers sell in decimal gigabytes while operating systems report in binary gibibytes, so a '500 GB' drive is about 465 GiB of usable, OS-reported space.
Common uses of gibibytes include: Operating-system storage and RAM reporting; Virtual-machine and disk-image sizing; Reconciling advertised vs. reported drive capacity; Exact power-of-two capacity in software.

Frequently asked questions
How many gibibytes are in one terabyte?
One terabyte (TB) equals 931.322575 gibibytes (GiB). Multiply any value in terabytes by 931.322575 to convert to gibibytes.
How do I convert terabytes to gibibytes?
Multiply the value in terabytes by 931.322575. For example, 5 TB × 931.322575 = 4,656.6129 GiB.
How do I convert gibibytes to terabytes?
Multiply the value in gibibytes by 0.001073741824, or divide by 931.322575. Use the swap button on the converter above to reverse the direction.
Is the terabyte to gibibyte conversion exact?
Decimal units (KB, MB, GB) use powers of 1000 per SI; binary units (KiB, MiB, GiB) use powers of 1024 per IEC. Both are exact — just be sure you are using the right family, since storage is often sold in decimal but reported by operating systems in binary.
What is the formula for terabytes to gibibytes?
The formula is: GiB = TB × 931.322575. This comes from the definition of both units relative to the byte.
