Conversion Formula
EiB = Pbit × 0.0001084202172
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.
About Exbibytes
An exbibyte (EiB) = 2⁶³ bytes ≈ 9.22 × 10¹⁸ bytes (IEC 80000-13). 2⁶³ is also the absolute value of INT64_MIN (the smallest signed 64-bit integer), making 1 EiB the natural upper limit for file systems using signed 64-bit byte offsets. File system theoretical maxima: NTFS 16 EiB; APFS 8 EiB; Btrfs 16 EiB; ZFS 256 quadrillion ZiB. Total hyperscale cloud storage estimated at 500-1,000 EiB as of 2024. 1 EiB = 2⁶⁰ bytes = 1,024 PiB.
