Megabits per Second to Mebibytes per Second (Mbps to MiB/s)

Formula

MiB/s = Mbps × 0.1192092895508

or MiB/s = Mbps ÷ 8.388608

Derivation from SI units:

• 1 Mbit/s = 10⁶ bit/s.
• 1 MiB/s = 1,048,576 B/s.
• 1 Mbps = 1000000 bps ÷ 8388608 bps per MiB/s = 0.1192092895508 MiB/s

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

Worked examples

1. A reading of 25 Mbps converts to 2.980232239 MiB/s.
   25 Mbps × 0.1192092896 = 2.980232239 MiB/s
2. A value of 200 Mbps is 23.84185791 MiB/s.
   200 Mbps × 0.1192092896 = 23.84185791 MiB/s

Where it's used

Megabits per Second are used for internet plans and speed tests, while mebibytes per second appear in file copy dialogs. Both measure data transfer rate (bandwidth), so the conversion is a fixed factor.
