Kibibytes per Second to Gigabytes per Second (KiB/s to GB/s)

Formula

GB/s = KiB/s × 0.000001024

or GB/s = KiB/s ÷ 976562.5

Derivation from SI units:

• 1 KiB/s = 1024 B/s.
• 1 GB/s = 10⁹ B/s = 8 Gbit/s.
• 1 KiB/s = 8192 bps ÷ 8000000000 bps per GB/s = 0.000001024 GB/s

Both units are defined exactly, so the factor is exact. Kibibyte per Second definition: kibibyte per second; Gigabyte per Second definition: gigabyte per second.

Worked examples

1. A reading of 25 KiB/s converts to 0.0000256 GB/s.
   25 KiB/s × 0.000001024 = 0.0000256 GB/s
2. A value of 200 KiB/s is 0.0002048 GB/s.
   200 KiB/s × 0.000001024 = 0.0002048 GB/s

Where it's used

Kibibytes per Second are used for linux command-line transfer speeds, while gigabytes per second appear in NVMe SSD speeds. Both measure data transfer rate (bandwidth), so the conversion is a fixed factor.
