Questions

How many terabytes are in a gibibyte?

One gibibyte is 0.00107374182 terabytes. To convert any amount, multiply by 0.00107374182. Going the other way, one terabyte is 931.322575 gibibytes.

What is the formula to convert GiB to TB?

Multiply the gibibyte figure by 0.00107374182. So TB = GiB × 0.00107374182. For a quick mental estimate, dividing by about 931.32 gets you close enough for most everyday purposes.

What does a gibibyte actually look like?

One gibibyte is what your OS calls a 'GB' of memory. A gibibyte is exactly 1,024³ bytes, about 7.4% more than a gigabyte. RAM is always sold in binary units even when storage is not.

And what is a terabyte?

One terabyte is a large photo and video library. A terabyte is a trillion bytes. Consumer drives are sold in decimal terabytes, which is why a '2 TB' drive shows as roughly 1.82 TiB once formatted.

Why does my 1 TB drive show as only 931 GB?

Because two different definitions are in play. Storage manufacturers use decimal units — 1 TB means exactly one trillion bytes. Windows and many other systems display binary units but label them with decimal names, so they show that same drive as 931 "GB" when they mean 931 gibibytes. Nothing is missing and nothing is faulty; the drive holds exactly what it says, measured differently. The IEC standardised kibi, mebi and gibi in 1998 specifically to end this, but adoption has been patchy.

Is this conversion exact?

Yes — both decimal and binary prefixes are exactly defined powers, so every figure here is exact rather than approximate. The results are shown to seven significant figures; the underlying arithmetic uses full double precision.

How to convert gibibytes to terabytes

Multiply by 0.00107374182. One gibibyte is 0.00107374182 terabytes, and one terabyte is 931.322575 gibibytes.

TB = GiB × 0.00107374182

Worked example

500 GiB = 0.5368709 TB. For a sense of scale, one gibibyte is what your OS calls a 'GB' of memory, and one terabyte is a large photo and video library.

Getting it right

The decimal and binary prefixes are the trap: a kilobyte is 1,000 bytes but a kibibyte is 1,024, and the gap compounds at every step until a terabyte and a tebibyte differ by about 10%. Storage manufacturers use decimal, operating systems often display binary, and neither is wrong — they are simply different units.
