Terabits per Second to Megabytes per Second (Tbps to MB/s)
1 terabit per second (Tbps) = 125000 megabytes per second (MB/s). 1 MB/s = 0.000008 Tbps. Example: 15 Tbps = 15 × 125000 = 1875000 MB/s.

How to Convert Terabit per Second to Megabyte per Second
- 1 Tbps = 125000 MB/s
- 1 MB/s = 0.000008 Tbps
- Example: convert 15 Tbps to MB/s: 15 Tbps = 15 × 125000 MB/s = 1875000 MB/s
Formula
MB/s = Tbps × 125000
Derivation from SI units:
- 1 Tbit/s = 10¹² bit/s.
- 1 MB/s = 10⁶ B/s = 8 Mbit/s.
- 1 Tbps = 1000000000000 bps ÷ 8000000 bps per MB/s = 125000 MB/s
Both units are defined exactly, so the factor is exact. Terabit per Second definition: terabit per second; Megabyte per Second definition: megabyte per second.
Worked examples
- A reading of 1 Tbps converts to 125000 MB/s.
1 Tbps × 125000 = 125000 MB/s - A value of 50 Tbps is 6250000 MB/s.
50 Tbps × 125000 = 6250000 MB/s

Where it's used
Terabits per Second are used for undersea fibre cables, while megabytes per second appear in download and copy speeds. Both measure data transfer rate (bandwidth), so the conversion is a fixed factor.
