Frequently asked questions

How many gibibytes are in a terabyte?

There are 931.323 gibibytes in one terabyte. To convert any amount, multiply the number of terabytes by 931.323.

How do I convert gibibytes back to terabytes?

Divide instead of multiplying, or equivalently multiply by 0.00107374. One gibibyte is 0.00107374 terabytes.

Is this conversion exact?

Yes, provided both sides use the same convention. Decimal units (KB, MB, GB) are powers of 1,000 and binary units (KiB, MiB, GiB) are powers of 1,024. Both are exact — the confusion comes from software labelling binary values with decimal names.

Where is each of these units used?

Terabytes: decimal terabyte — 1,000,000,000,000 bytes. Gibibytes: binary gigabyte — 1,024³ bytes, about 7.4% larger than a decimal GB.
