Convert Terabits to Petabits
Convert Terabits (Tbit) to Petabits (Pbit) instantly and accurately.
Conversion Formula
Pbit = Tbit × 0.001
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 Petabits
A petabit (Pbit) = 10¹⁵ bits (SI). Major internet exchange points (DE-CIX, AMS-IX) handle peak traffic of multi-Tbit/s, accumulating Pbits per hour. Bell Labs (2022) achieved 1.02 Pbit/s over a single fibre pair. CERN LHC distributes ≈ 720 Pbit/year through the WLCG computing grid. 100 wavelengths at 800 Gbit/s each = 80 Tbit/s per fibre; ≈13 such fibres = 1 Pbit/s. 1 Pbit = 10¹⁵ bits = 125 TB.
