How to convert terabytes to tebibytes
To convert a measurement in terabytes to tebibytes, multiply the value by 0.909494701773. The conversion factor comes from the relationship between both units and the byte.
For example, to convert 5 TB to tebibytes: 5 × 0.909494701773 = 4.547474 TiB.
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 tebibyte?
A tebibyte is exactly 1,099,511,627,776 bytes (2^40), the binary counterpart of the terabyte defined by the IEC. As storage reached the terabyte scale, the gap between decimal and binary units grew to about 10%, making the IEC's tebibyte useful whenever an exact power-of-two capacity must be stated unambiguously.
Common uses of tebibytes include: Large drive and array capacity in operating systems; NAS and RAID usable-space calculations; Backup and archival capacity planning; Exact power-of-two measurement at terabyte scale.

Frequently asked questions
How many tebibytes are in one terabyte?
One terabyte (TB) equals 0.909494701773 tebibytes (TiB). Multiply any value in terabytes by 0.909494701773 to convert to tebibytes.
How do I convert terabytes to tebibytes?
Multiply the value in terabytes by 0.909494701773. For example, 5 TB × 0.909494701773 = 4.547474 TiB.
How do I convert tebibytes to terabytes?
Multiply the value in tebibytes by 1.099512, or divide by 0.909494701773. Use the swap button on the converter above to reverse the direction.
Is the terabyte to tebibyte 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 tebibytes?
The formula is: TiB = TB × 0.909494701773. This comes from the definition of both units relative to the byte.
