Convert Bits to Petabits
Convert Bits (b) to Petabits (Pbit) instantly and accurately.
Conversion Formula
Pbit = b × 1.000000000e-15
About Bits
The bit (b) is the fundamental unit of digital information - a single binary digit: 0 or 1. Coined by John Tukey in 1948; formalised by Claude Shannon. Physically realised as transistor states (SRAM/DRAM), magnetic domains (HDD), charge levels in NAND flash (MLC=2, TLC=3, QLC=4 bits per cell). Shannon entropy: a coin flip = 1 bit; a card drawn from a 52-card deck ≈ 5.7 bits. 1 bit = 1/4 nibble = 1/8 byte.
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.
