Answers as you type
No button, no wait. The worked answer is already on the page before any script runs.
Kibibyte and Gigabyte
A kibibyte is exactly 1,024 bytes. The name was coined in 1998 precisely so that "kilobyte" could go back to meaning 1,000, though the habit never fully took.
A gigabyte is a billion bytes in the decimal sense used by drive manufacturers, phone plans and video sizes.

Convert KiB to GB: common questions
How many gigabytes are in a kibibyte?
Exactly 0.000001024. One kibibyte is 0.000001024 gigabytes, and the box above will do it for any figure you type.
Is this conversion exact, or rounded?
The ratio is exact. It is not a rounded constant typed into a table: it is derived from the definitions of the two units, so it agrees with any other correct converter to as many digits as you care to compare.
Why does another converter show a slightly different number?
Almost always rounding rather than disagreement. Many converters cut the answer to two or four decimals, and some carry a factor that was rounded before the multiplication rather than after. The figures here are computed from the exact definitions and only rounded on the way to the screen.
Where these figures come from
The claims this page makes about data units are checkable, and these are the documents that settle them.
How this page works
The factor is a constant in the page and the arithmetic is four operations, so nothing is sent anywhere and nothing needs to be. The number you type never leaves the browser — there is no request for it to travel in.
