Convert Petabits per second to Bytes per second
Convert Petabits per second (Pbit/s) to Bytes per second (B/s) instantly and accurately.
Conversion Formula
B/s = Pbit/s × 125000000000000
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 Bytes per second
Byte per second (B/s) = 8 bit/s. The natural unit for file transfer speeds, disk I/O, and memory bandwidth reported by OS tools and storage benchmarks. ISP 'Mbit/s' ÷ 8 = MB/s download speed: a 100 Mbit/s connection delivers ≈ 12.5 MB/s. USB 2.0 = 60 MB/s; SATA III = 600 MB/s; Thunderbolt 4 = 5,000 MB/s. 1 B/s = 8 bit/s.
