Gibibytes to Bytes Converter

About the gib to b calculation

One gibibyte is exactly 1,073,741,824 bytes, 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. Eight bits, and the base unit every other storage figure is built from.

Formula

B = GiB × 1,073,741,824

1 GiB = 1,073,741,824 B
1 B = 9.3132e-10 GiB

Worked example

To convert 1 GiB, multiply by 1,073,741,824: 1 × 1,073,741,824 = 1,073,741,824 B.

Frequently asked questions

How many bytes are in a gibibyte?

There are 1,073,741,824 bytes in one gibibyte. To convert any amount, multiply the number of gibibytes by 1,073,741,824.

How do I convert bytes back to gibibytes?

Divide instead of multiplying, or equivalently multiply by 9.3132e-10. One byte is 9.3132e-10 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. Bytes: eight bits, and the base unit every other storage figure is built from.
