Convert Kilobytes to Gigabytes (kB to GB)
1 kilobyte (kB) = 0.000001 gigabytes (GB). 1 GB = 1000000 kB. Example: 15 kB = 15 × 0.000001 = 0.000015 GB.
Also searched as kilobytes to GB, kilobytes in GB, kilobytes into gigabytes, kB to GB, kB in gigabytes, kB into gigabyte, kilobyte to gigabyte, kB to gigabytes converter and how many gigabytes in a kilobyte.

How to Convert Kilobyte to Gigabyte
- 1 kB = 0.000001 GB
- 1 GB = 1000000 kB
- Example: convert 15 kB to GB: 15 kB = 15 × 0.000001 GB = 0.000015 GB
Formula
GB = kB ÷ 1000000
Derivation from SI units:
- 1 kB = 1000 bytes = 8000 bits (decimal, SI).
- 1 GB = 10⁹ bytes = 8 × 10⁹ bits (decimal, SI).
- 1 kB = 8000 bit ÷ 8000000000 bit per GB = 0.000001 GB
Both units are defined exactly, so the factor is exact. Kilobyte definition: kilobyte; Gigabyte definition: gigabyte.
Worked examples
- A reading of 16 kB converts to 0.000016 GB.
16 kB × 0.000001 = 0.000016 GB - A value of 128 kB is 0.000128 GB.
128 kB × 0.000001 = 0.000128 GB

Frequently asked questions
How many gigabytes are in 1 kilobyte?
1 kB = 0.000001 GB.
How do I convert kilobytes to gigabytes?
Multiply the value in kB by 0.000001, or divide it by 1000000. For example, 15 kB × 0.000001 = 0.000015 GB.
Is the kB to GB conversion exact?
Yes. Both units are defined exactly, and 1 kB is exactly 0.000001 GB.
