Mebibytes per Second to Gigabytes per Second (MiB/s to GB/s)

Formula

GB/s = MiB/s × 0.001048576

or GB/s = MiB/s ÷ 953.6743164063

Derivation from SI units:

• 1 MiB/s = 1,048,576 B/s.
• 1 GB/s = 10⁹ B/s = 8 Gbit/s.
• 1 MiB/s = 8388608 bps ÷ 8000000000 bps per GB/s = 0.001048576 GB/s

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

Worked examples

1. A reading of 25 MiB/s converts to 0.0262144 GB/s.
   25 MiB/s × 0.001048576 = 0.0262144 GB/s
2. A value of 200 MiB/s is 0.2097152 GB/s.
   200 MiB/s × 0.001048576 = 0.2097152 GB/s

Where it's used

Mebibytes per Second are used for file copy dialogs, while gigabytes per second appear in NVMe SSD speeds. Both measure data transfer rate (bandwidth), so the conversion is a fixed factor.
