Convert terabytes to tebibytes
tebibytes = terabytes × 0.909495
One terabyte is 0.909495 tebibytes, so multiply by 0.909495 to convert. Going the other way, one tebibyte is 1.0995 terabytes. This is the conversion behind a drive that seems to lose space: manufacturers sell decimal units (1 TB = 10¹² bytes) while Windows displays binary ones (1 TiB = 2⁴⁰ bytes) under the label “TB”. Nothing is missing — the same bytes are being counted in a bigger unit.
