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.
About Kilobytes per second
Kilobyte per second (KB/s) = 1,000 B/s = 8,000 bit/s (SI). Legacy modem throughput: 56 kbit/s dial-up ≈ 7 KB/s; ISDN 128 kbit/s = 16 KB/s. RS-232 at 115,200 baud (8N1) = 11.52 KB/s. CD-ROM 1× = 150 KB/s; 52× = 7,800 KB/s. Bluetooth 2.1 EDR ≈ 300 KB/s; USB 1.1 Full Speed = 1,500 KB/s. 1 KB/s = 1,000 B/s = 8 kbit/s.
