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).[1] Its unit symbol is TiB.

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

1 tebibyte = 240 bytes = 1099511627776bytes = 1024 gibibytes
1024 TiB = 1 pebibyte (PiB)

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.[2] (see Consumer confusion).
