Terabits per Second to Bytes per Second (Tbps to B/s)
1 terabit per second (Tbps) = 125000000000 bytes per second (B/s). 1 B/s = 8 × 10⁻¹² Tbps. Example: 15 Tbps = 15 × 125000000000 = 1875000000000 B/s.

How to Convert Terabit per Second to Byte per Second
- 1 Tbps = 125000000000 B/s
- 1 B/s = 8 × 10⁻¹² Tbps
- Example: convert 15 Tbps to B/s: 15 Tbps = 15 × 125000000000 B/s = 1875000000000 B/s
Formula
B/s = Tbps × 125000000000
Derivation from SI units:
- 1 Tbit/s = 10¹² bit/s.
- 1 B/s = 8 bit/s.
- 1 Tbps = 1000000000000 bps ÷ 8 bps per B/s = 125000000000 B/s
Both units are defined exactly, so the factor is exact. Terabit per Second definition: terabit per second; Byte per Second definition: byte per second.
Worked examples
- A reading of 1 Tbps converts to 125000000000 B/s.
1 Tbps × 125000000000 = 125000000000 B/s - A value of 50 Tbps is 6250000000000 B/s.
50 Tbps × 125000000000 = 6250000000000 B/s

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