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

Formula

KiB/s = GB/s × 976562.5

Derivation from SI units:

• 1 GB/s = 10⁹ B/s = 8 Gbit/s.
• 1 KiB/s = 1024 B/s.
• 1 GB/s = 8000000000 bps ÷ 8192 bps per KiB/s = 976562.5 KiB/s

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

Worked examples

1. A reading of 2 GB/s converts to 1953125 KiB/s.
   2 GB/s × 976562.5 = 1953125 KiB/s
2. A value of 7 GB/s is 6835937.5 KiB/s.
   7 GB/s × 976562.5 = 6835937.5 KiB/s

Where it's used

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