About Kilobits

A kilobit (kbit) = 1,000 bits (SI). Standard unit for connection speeds: dial-up 9.6-56 kbit/s; ISDN 64-128 kbit/s; early ADSL 256 kbit/s. VoIP codecs: G.711 = 64 kbit/s; Opus (WhatsApp, Discord) = 6-510 kbit/s adaptive. Bluetooth LE up to 1,000 kbit/s; Zigbee/Z-Wave 20-250 kbit/s. 'kbit/s' = strictly decimal 1,000 bits/s (ITU/IEEE). 1 kbit = 1,000 bits = 125 bytes.

About Kilobytes

A kilobyte (KB) = 1,000 bytes (SI). Used by all storage manufacturers (HDD, SSD, USB, SD) and endorsed by the IEC and FTC. Typical sizes: plain-text email 2-5 KB; HTML page 10-100 KB; Word document 10-30 KB. Ethernet MTU = 1,500 bytes ≈ 1.5 KB; jumbo frames 9 KB. MP3 at 128 kbit/s = 16 KB/s of audio. 1 KB = 1,000 bytes = 8,000 bits.
