Gigabytes per Second to Kilobytes per Second (GB/s to kB/s)
1 gigabyte per second (GB/s) = 1000000 kilobytes per second (kB/s). 1 kB/s = 0.000001 GB/s. Example: 15 GB/s = 15 × 1000000 = 15000000 kB/s.

How to Convert Gigabyte per Second to Kilobyte per Second
- 1 GB/s = 1000000 kB/s
- 1 kB/s = 0.000001 GB/s
- Example: convert 15 GB/s to kB/s: 15 GB/s = 15 × 1000000 kB/s = 15000000 kB/s
Formula
kB/s = GB/s × 1000000
Derivation from SI units:
- 1 GB/s = 10⁹ B/s = 8 Gbit/s.
- 1 kB/s = 1000 B/s = 8000 bit/s.
- 1 GB/s = 8000000000 bps ÷ 8000 bps per kB/s = 1000000 kB/s
Both units are defined exactly, so the factor is exact. Gigabyte per Second definition: gigabyte per second; Kilobyte per Second definition: kilobyte per second.
Worked examples
- A reading of 2 GB/s converts to 2000000 kB/s.
2 GB/s × 1000000 = 2000000 kB/s - A value of 7 GB/s is 7000000 kB/s.
7 GB/s × 1000000 = 7000000 kB/s
