Convert Terabits per second to Bytes per second
Convert Terabits per second (Tbit/s) to Bytes per second (B/s) instantly and accurately.
Conversion Formula
B/s = Tbit/s × 125000000000
About Terabits per second
Terabit per second (Tbit/s) = 10¹² bit/s (SI). Internet backbone scale: MAREA cable (2017) = 200 Tbit/s per fibre pair; 2Africa cable (2024) = 180 Tbit/s. DWDM: 100 wavelengths × 800 Gbit/s = 80 Tbit/s per fibre. H100 GPU HBM3 memory bandwidth = 3.35 Tbit/s per GPU. NTT lab record (2023): 1,200 Tbit/s over a single fibre. 1 Tbit/s = 10¹² bit/s = 125 GB/s.
About Bytes per second
Byte per second (B/s) = 8 bit/s. The natural unit for file transfer speeds, disk I/O, and memory bandwidth reported by OS tools and storage benchmarks. ISP 'Mbit/s' ÷ 8 = MB/s download speed: a 100 Mbit/s connection delivers ≈ 12.5 MB/s. USB 2.0 = 60 MB/s; SATA III = 600 MB/s; Thunderbolt 4 = 5,000 MB/s. 1 B/s = 8 bit/s.
