How to convert terabytes to tebibytes
To convert terabytes (TB) to tebibytes (TiB), multiply the value in terabytes by 0.909494701773.
TiB = TB × 0.909494701773 (decimal)
TiB = TB × 1 (binary)
Example: 5 TB = 4.547473509 TiB, or 5 TiB in binary.
Decimal (SI) counting steps by 1,000 and is what drive makers, macOS and phones use. Binary counting steps by 1,024 and is what Windows and RAM use; its unambiguous IEC names are KiB, MiB and GiB. Bits are decimal either way.
You can also type 5 TB to TiB into the smart calculator, or mix units: 1 TB + 1 TiB.

About the units
Terabyte (TB)
In decimal mode 1,000 GB, which is how drives are sold; in binary mode 1,024 GB.
Tebibyte (TiB)
Exactly 1,024 GiB.
Digital storage is counted in bits and bytes (1 byte = 8 bits). There are two ways to count bytes. Decimal (SI) prefixes step by 1,000: 1 KB = 1,000 B and 1 GB = 1,000 MB, which is how drive makers, macOS, iOS and Android report sizes. Binary prefixes step by 1,024: 1 KB = 1,024 B and 1 GB = 1,024 MB, which is how Windows and RAM count (the IEC names for these are KiB, MiB and GiB). Bits are always decimal: 1 Kb = 1,000 b.
Questions and answers
How many tebibytes are in a terabyte?
One terabyte (TB) equals 0.9094947018 tebibytes in decimal (SI) counting, or 1 tebibytes in binary counting (1 KB = 1,024 B), which Windows uses.
How do I convert terabytes to tebibytes?
To convert terabytes to tebibytes, multiply the value in terabytes by 0.909494701773. The formula is TiB = TB × 0.909494701773. For example, 5 TB = 4.5474735 TiB.
What is 5 TB in TiB?
5 terabytes is 4.547473509 tebibytes.
Which is bigger, a terabyte or a tebibyte?
A tebibyte is bigger: 1 TiB = 1.099511628 TB.
Is 1 GB equal to 1,000 MB or 1,024 MB?
Both are in use. In decimal (SI) counting, which drive makers, macOS, iOS and Android use, 1 GB = 1,000 MB. In binary counting, which Windows and RAM use, 1 GB = 1,024 MB; the unambiguous IEC name for that size is the gibibyte (GiB). ConvertEasy has a Decimal / Binary switch so KB, MB, GB and TB follow whichever you need, while KiB, MiB and GiB are always binary.
Are kilobits 1,000 or 1,024 bits?
ConvertEasy treats bits as decimal in both modes: 1 Kb = 1,000 b, 1 Mb = 1,000 Kb. A byte is always 8 bits, so only byte units (KB, MB, GB…) change with the switch.
Does this TB to TiB converter work offline?
Yes. ConvertEasy is a progressive web app: after your first visit it keeps working with no connection, and you can install it to your home screen from the browser menu.
