How the conversion works
Multiply by 931.3225746 to go from terabytes to gibibytes, or by 0.001073741824 to go back the other way. Both figures are exact rather than rounded: they follow from the definitions of the units, not from anybody measuring something.
This is why a drive sold as 1 TB shows up as roughly 931 GB. The manufacturer counts a terabyte as a million million bytes, which is correct, and the operating system divides by 1,024 three times while still writing GB, which is also defensible. Nothing is missing and nobody is lying.
