How to convert gigabytes to kilobytes
kB = GB × 1,000,000Multiply the value in gigabytes by 1,000,000. To go the other way, multiply by 0.000001 (or divide by 1,000,000).
A gigabyte is larger than a kilobyte: one gigabyte contains 1,000,000 kilobytes.

About the units
Gigabyte (GB)
10⁹ bytes. Phone storage, data plans and RAM are sold in GB. One gigabyte equals 8,000,000,000 bits (b).
Kilobyte (kB)
1,000 bytes (decimal). Some software still uses “KB” for 1,024 bytes; that is properly a kibibyte (KiB). One kilobyte equals 8,000 bits (b).
Frequently asked questions
How many kilobytes are in one gigabyte?
There are 1,000,000 kilobytes in one gigabyte, and this value is exact by definition.
How do I convert gigabytes to kilobytes?
Multiply the number of gigabytes by 1,000,000. For example, 10 GB × 1,000,000 = 10,000,000 kB.
How many gigabytes are in one kilobyte?
One kilobyte equals 0.000001 gigabytes. That is the reverse factor, 1 ÷ 1,000,000.
What is 10 gigabytes in kilobytes?
10 GB = 10,000,000 kB.
Is this GB to kB converter accurate?
Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
