Gibibytes to Gigabytes Converter

About the gib to gb calculation

One gibibyte is exactly 1.0737 gigabytes, so converting between them is a single multiplication. Enter any value above and the result updates as you type. Binary gigabyte — 1,024³ bytes, about 7.4% larger than a decimal GB. Decimal gigabyte. This is why a "1 TB" drive shows as roughly 931 GB in your operating system.

Formula

GB = GiB × 1.0737

1 GiB = 1.0737 GB
1 GB = 0.931323 GiB

Worked example

To convert 1 GiB, multiply by 1.0737: 1 × 1.0737 = 1.0737 GB.

Frequently asked questions

How many gigabytes are in a gibibyte?

There are 1.0737 gigabytes in one gibibyte. To convert any amount, multiply the number of gibibytes by 1.0737.

How do I convert gigabytes back to gibibytes?

Divide instead of multiplying, or equivalently multiply by 0.931323. One gigabyte is 0.931323 gibibytes.

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?

Gibibytes: binary gigabyte — 1,024³ bytes, about 7.4% larger than a decimal GB. Gigabytes: decimal gigabyte. This is why a "1 TB" drive shows as roughly 931 GB in your operating system.
