Bytes to Gibibytes Converter

About the b to gib calculation

One byte is exactly 9.3132e-10 gibibytes, so converting between them is a single multiplication. Enter any value above and the result updates as you type. Eight bits, and the base unit every other storage figure is built from. Binary gigabyte — 1,024³ bytes, about 7.4% larger than a decimal GB.

Formula

GiB = B × 9.3132e-10

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

Worked example

To convert 1,024 B, multiply by 9.3132e-10: 1,024 × 9.3132e-10 = 9.5367e-7 GiB.

Frequently asked questions

How many gibibytes are in a byte?

There are 9.3132e-10 gibibytes in one byte. To convert any amount, multiply the number of bytes by 9.3132e-10.

How do I convert gibibytes back to bytes?

Divide instead of multiplying, or equivalently multiply by 1,073,741,824. One gibibyte is 1,073,741,824 bytes.

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?

Bytes: eight bits, and the base unit every other storage figure is built from. Gibibytes: binary gigabyte — 1,024³ bytes, about 7.4% larger than a decimal GB.
