In 1 kilobytes there are 0.00000100000 gigabytes. Meanwhile in 1 gigabytes there are 1,000,000 kilobytes. Keep reading to learn more about each unit of measure and how they are calculated. Or just use the Gigabytes to Kilobytes calculator above to convert any number.

To convert kilobytes (KB) to gigabytes (GB), you need the right unit base. Most computers use the binary base where 1,024 is the key number.
Example:
Tip: If you’re converting KB to GB for file sizes, use the 1,024-based method for the most common result.
It depends on the system you use. In the decimal system, used by many storage makers, 1 GB equals 1,000,000 KB. In the binary system, used often in computers, 1 GB equals 1,048,576 KB.
Decimal units use powers of 1,000 (KB, MB, GB). Binary units use powers of 1,024 and are often shown as KiB, MiB, and GiB. That gap is why a “1 GB” file can show a different size on a computer.
Both numbers are correct, but they mean different things.
Use the system you need:
Multiply instead of divide:
Drive labels often use decimal GB (1 GB = 1,000,000,000 bytes). Many computers report space in binary units (GiB) but may still show “GB” on screen. The number looks smaller because GiB is a larger unit than decimal GB.
They’re not the same, even if they’re used that way in some apps.
In decimal terms:
In binary terms:
Download speeds often use decimal units (like Mbps). File sizes can show decimal or binary, based on the device or app. If the numbers don’t match, it’s usually a decimal vs binary issue, not missing data.
For a fast decimal estimate, move the decimal six places:
No. Conversion only changes how the size is shown. The file content stays the same, and the byte count doesn’t change.
For most everyday use, decimal GB is fine. Use binary (GiB) when you need a closer match to what your computer reports, or when comparing drive space shown by the system.
The Calculate Box tool to convert kilobytes to gigabytes uses the open source script Convert.js to convert units of measurement. To use this tool, simply type a kilobytes value in the box and have it instantly converted to gigabytes.
