The **tebibyte** is a multiple of the unit byte for digital information. It is a member of the set of units with binary prefixes defined by the International Electrotechnical Commission (IEC).^{[1]} Its unit symbol is **TiB**.

The prefix tebi (symbol **Ti**) represents multiplication by 1024^{4}, therefore:

- 1024 TiB = 1 pebibyte (PiB)

The tebibyte is closely related to the terabyte (TB), which is defined as 10^{12} bytes = 1000000000000bytes. It follows that one tebibyte (1 TiB) is approximately equal to 1.1 TB.
In some contexts, the terabyte has been used as a synonym for tebibyte.^{[2]} (see Consumer confusion).
