Convert Bits per second to Bytes per second
Convert Bits per second (bit/s) to Bytes per second (B/s) instantly and accurately.
Conversion Formula
B/s = bit/s × 0.125
About Bits per second
Bit per second (bit/s) is the fundamental SI data-rate unit - one binary digit transmitted per second. Shannon's channel capacity C = B log₂(1 + S/N) expresses maximum achievable bit/s. Early RS-232 serial links ran at 110-9,600 bit/s; GSM voice uses 13 kbit/s; a coin-flip entropy source produces 1 bit/s per flip. 1 bit/s = 0.125 B/s = 10⁻³ kbit/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.
