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.

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.
