Convert Petabits per second to Exabits per second
Convert Petabits per second (Pbit/s) to Exabits per second (Ebit/s) instantly and accurately.
Conversion Formula
Ebit/s = Pbit/s × 0.001
About Petabits per second
Petabit per second (Pbit/s) = 10¹⁵ bit/s (SI). Research-scale only: NTT (2024) achieved 1.53 Pbit/s over a single fibre using space + wavelength division multiplexing. The combined peak of the world's largest internet exchange points (DE-CIX, AMS-IX) is multi-Tbit/s. Global IP traffic ≈ 1.8 Pbit/s sustained average in 2030 forecast. 1 Pbit/s = 10¹⁵ bit/s = 125 TB/s.
About Exabits per second
Exabit per second (Ebit/s) = 10¹⁸ bit/s (SI). Theoretical: Shannon limit for a single-mode fibre over 50 THz optical bandwidth ≈ 100 Pbit/s - still ~10,000× below 1 Ebit/s. Reaching 1 Ebit/s would require ≈1 million parallel fibres each at 1 Pbit/s. Global internet backbone installed capacity in 2024 ≈ 5-10 Pbit/s. 1 Ebit/s = 10¹⁸ bit/s = 125 PB/s.
