Conversion Formula
KB = Tbit × 125000000
About Terabits
A terabit (Tbit) = 10¹² bits (SI). Submarine cable capacity: 2Africa cable (2024) designed at 180 Tbit/s; MAREA (2017) at 160 Tbit/s. Data-centre interconnects use 400 Gbit/s (0.4 Tbit/s) per link. PCIe 6.0 ×16 delivers ≈0.5 Tbit/s aggregate. NVMe RAID arrays with 100+ PCIe 5.0 SSDs approach 1 Tbit/s aggregate sequential read. 1 Tbit = 10¹² bits = 125 GB.
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.
