Convert Bytes per second to Petabytes per second
Convert Bytes per second (B/s) to Petabytes per second (PB/s) instantly and accurately.
Conversion Formula
PB/s = B/s × 1.000000000e-15
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.
About Petabytes per second
Petabyte per second (PB/s) = 10¹⁵ B/s (SI). Theoretical for single systems. NTT 2024 fibre lab record = 191 TB/s ≈ 0.19 PB/s. Exascale HPC with 10,000 nodes × 10 TB/s memory bandwidth each = 100,000 TB/s = 100 PB/s in aggregate - plausible as a cluster total but not a single link. Global all-data-centre combined write throughput ≈ 1-10 PB/s. 1 PB/s = 10¹⁵ B/s = 8 Pbit/s.
