How to convert kilobytes to gigabytes
To convert a measurement in kilobytes to gigabytes, multiply the value by 0.000001. The conversion factor comes from the relationship between both units and the byte.
For example, to convert 5 KB to gigabytes: 5 × 0.000001 = 0.000005 GB.
What is a kilobyte?
A kilobyte is 1,000 bytes under the SI decimal convention. Note that some contexts historically used 1,024 bytes; the 1,024-byte unit is properly the kibibyte (KiB). The 'kilo' prefix means 1,000 in SI, but early computing loosely used kilobyte for 1,024 bytes because it is close to 2^10. This ambiguity led the IEC to introduce the binary 'kibibyte' in 1998 to keep the two meanings distinct.
Common uses of kilobytes include: Small text documents and configuration files; Email message sizes; Web page and icon asset sizes; Marketing of storage where decimal units are used.
What is a gigabyte?
A gigabyte is 1,000,000,000 bytes (1,000 megabytes) under the SI decimal convention. The binary equivalent of 1,073,741,824 bytes is the gibibyte (GiB). The gigabyte became the standard consumer storage unit with the rise of hard drives, USB sticks, and smartphones. Drive makers market capacity in decimal gigabytes, while operating systems often report in binary gibibytes, which is why a '500 GB' drive shows as about 465 GB.
Common uses of gigabytes include: Hard drive, SSD, and USB flash storage capacity; Smartphone and tablet storage tiers; HD video and large software installs; RAM and memory-card sizing.

Frequently asked questions
How many gigabytes are in one kilobyte?
One kilobyte (KB) equals 0.000001 gigabytes (GB). Multiply any value in kilobytes by 0.000001 to convert to gigabytes.
How do I convert kilobytes to gigabytes?
Multiply the value in kilobytes by 0.000001. For example, 5 KB × 0.000001 = 0.000005 GB.
How do I convert gigabytes to kilobytes?
Multiply the value in gigabytes by 1,000,000, or divide by 0.000001. Use the swap button on the converter above to reverse the direction.
Is the kilobyte to gigabyte conversion exact?
Decimal units (KB, MB, GB) use powers of 1000 per SI; binary units (KiB, MiB, GiB) use powers of 1024 per IEC. Both are exact — just be sure you are using the right family, since storage is often sold in decimal but reported by operating systems in binary.
What is the formula for kilobytes to gigabytes?
The formula is: GB = KB × 0.000001. This comes from the definition of both units relative to the byte.
