Convert Gigabits per second to Bytes per second
Convert Gigabits per second (Gbit/s) to Bytes per second (B/s) instantly and accurately.
Conversion Formula
B/s = Gbit/s × 125000000
About Gigabits per second
Gigabit per second (Gbit/s) = 10⁹ bit/s (SI). Enterprise/data-centre standard: 1/10/25/100/400 Gbit/s Ethernet all deployed. Storage: SATA III = 6 Gbit/s; PCIe 4.0 ×4 = 64 Gbit/s; PCIe 5.0 ×4 = 128 Gbit/s. Display: HDMI 2.1 = 48 Gbit/s; DisplayPort 2.1 = 80 Gbit/s. Memory: DDR5-4800 dual-channel = 76.8 Gbit/s; H100 HBM3 = 26.8 Tbit/s. 1 Gbit/s = 10⁹ bit/s = 125 MB/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.
