About Megabits

A megabit (Mbit) = 1,000,000 bits (SI). Everyday unit for broadband speeds: ADSL2+ up to 24 Mbit/s; VDSL2 up to 100 Mbit/s; GPON fibre 100-10,000 Mbit/s; 5G NR 100-400 Mbit/s. Streaming: Netflix 1080p = 5 Mbit/s; 4K HDR = 15-25 Mbit/s. Wi-Fi 7 = 46,120 Mbit/s theoretical. ISP 'Mbps' = megabits/s; 'MB/s' (megabytes) is 8× larger. 1 Mbit = 1,000,000 bits = 125,000 bytes.

About Kibibits

A kibibit (Kibit) = 2¹⁰ = 1,024 bits (IEC 80000-13) - the binary counterpart to the kilobit. Defined to eliminate ambiguity between 1,000-bit and 1,024-bit 'kilobits'. Used in FPGA/ASIC block RAM sizing (a 32 Kibit block RAM = 4,096 bytes) and JEDEC DRAM specs. RSA key lengths (e.g. '4096-bit') are exact counts, unaffected by the kib/kb distinction. 1 Kibit = 1,024 bits = 128 bytes.
