Conversion Formula
Zbit/s = KB/s × 8.000000000e-18
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.
About Zettabits per second
Zettabit per second (Zbit/s) = 10²¹ bit/s (SI). Entirely theoretical. The entire global internet traffic in all of 2024 (≈40 Zbit) could be transferred in ≈40 seconds at 1 Zbit/s. The full electromagnetic spectrum (radio to gamma, ≈10³⁰ Hz bandwidth) at Shannon capacity still cannot sustain 1 Zbit/s with any known physical medium. 1 Zbit/s = 10²¹ bit/s = 125 EB/s.
