Tebibyte

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). Its unit symbol is TiB.

The prefix tebi (symbol Ti) represents multiplication by 1024⁴, therefore:

The tebibyte is closely related to the terabyte (TB), which is defined as 10¹² 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. (see Consumer confusion).
