Convert Bits per second to Kilobits per second
Convert Bits per second (bit/s) to Kilobits per second (kbit/s) instantly and accurately.
Conversion Formula
kbit/s = bit/s × 0.001
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 Kilobits per second
Kilobit per second (kbit/s) = 1,000 bit/s (SI). The classic unit for narrowband telecoms: dial-up (V.90) = 56 kbit/s; ISDN BRI = 64-128 kbit/s; G.711 VoIP = 64 kbit/s; Opus (WhatsApp, Discord) = 6-510 kbit/s adaptive; Bluetooth Classic = 1,000 kbit/s; Zigbee/Z-Wave = 20-250 kbit/s. 1 kbit/s = 1,000 bit/s = 125 B/s.
