Conversion Formula
GiB = Tbit × 116.4153218
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 Gibibytes
A gibibyte (GiB) = 2³⁰ = 1,073,741,824 bytes (IEC 80000-13). The source of the 'storage discrepancy': a '500 GB' drive contains 500×10⁹ bytes ≈ 465.66 GiB as shown by Windows. RAM is manufactured in exact powers of 2: 4/8/16/32/64 GiB. GPU VRAM: RTX 4090 = 24 GiB; H100 = 80 GiB; MI300X = 192 GiB HBM3. Kubernetes memory limits use Gi suffixes. 1 GiB = 2³⁰ bytes = 1,024 MiB.
