Mebibytes per Second to Terabits per Second (MiB/s to Tbps)

Formula

Tbps = MiB/s × 0.000008388608

or Tbps = MiB/s ÷ 119209.2895508

Derivation from SI units:

• 1 MiB/s = 1,048,576 B/s.
• 1 Tbit/s = 10¹² bit/s.
• 1 MiB/s = 8388608 bps ÷ 1000000000000 bps per Tbps = 0.000008388608 Tbps

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

Worked examples

1. A reading of 25 MiB/s converts to 0.0002097152 Tbps.
   25 MiB/s × 0.000008388608 = 0.0002097152 Tbps
2. A value of 200 MiB/s is 0.0016777216 Tbps.
   200 MiB/s × 0.000008388608 = 0.0016777216 Tbps

Where it's used

Mebibytes per Second are used for file copy dialogs, while terabits per second appear in undersea fibre cables. Both measure data transfer rate (bandwidth), so the conversion is a fixed factor.
