Gibibytes to Kilobytes Converter

About the gib to kb calculation

One gibibyte is exactly 1,073,741.82 kilobytes, 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 kilobyte — 1,000 bytes. Windows and macOS often mean 1,024 when they write "KB".

Formula

KB = GiB × 1,073,741.82

1 GiB = 1,073,741.82 KB
1 KB = 9.3132e-7 GiB

Worked example

To convert 1 GiB, multiply by 1,073,741.82: 1 × 1,073,741.82 = 1,073,741.82 KB.

Frequently asked questions

How many kilobytes are in a gibibyte?

There are 1,073,741.82 kilobytes in one gibibyte. To convert any amount, multiply the number of gibibytes by 1,073,741.82.

How do I convert kilobytes back to gibibytes?

Divide instead of multiplying, or equivalently multiply by 9.3132e-7. One kilobyte is 9.3132e-7 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. Kilobytes: decimal kilobyte — 1,000 bytes. Windows and macOS often mean 1,024 when they write "KB".
