Tebibytes to gibibytes (TiB to GiB)

One tebibyte is exactly 1,024 gibibytes. That is the definition of the prefixes, not a measurement: the decimal SI prefixes (kilo, mega, giga, tera) step by exactly 1,000, and the binary IEC prefixes (kibi, mebi, gibi, tebi) step by exactly 1,024. The two families are both exact; the trouble is only that software and storage labels do not always say which one they mean.

Worked through: 8 TiB x 1,024 = 8,192 GiB.

Going the other way, one gibibyte is 0.0009765625 tebibytes.

For mental arithmetic: Multiply by 1,024. 2 TiB is 2,048 GiB and 16 TiB is 16,384 GiB.

Exactly 1,024 GiB to the TiB. The usual reason to go this way is a provisioning form that takes gibibytes when the plan was written in tebibytes: a block volume quoted at a 16 TiB maximum is 16,384 GiB, and typing 16,000 leaves 384 GiB, about 2.3%, unallocated. Both units are binary, so there is no decimal-versus-binary question in this step; that only arises when one side is TB or GB.

Precision is worth matching to the input. A measurement given as 0.5 TiB carries one or two significant figures, and reporting its conversion to six implies a precision the original never had.
