Convert Kibibytes per second to Bytes per second
Convert Kibibytes per second (KiB/s) to Bytes per second (B/s) instantly and accurately.
Conversion Formula
B/s = KiB/s × 1024
About Kibibytes per second
Kibibyte per second (KiB/s) = 2¹⁰ = 1,024 B/s = 8,192 bit/s (IEC 80000-13). Used in embedded I/O specs and real-time OS throughput documentation. SD card speed classes: Class 10 = 10,000 KB/s ≈ 9,766 KiB/s; UHS-3 = 30,000 KB/s ≈ 29,297 KiB/s. STM32F4 FLASH page write ≈ 16 KiB/s; Arduino Uno SPI at 4 MHz = 500 KiB/s. 1 KiB/s = 1,024 B/s = 8,192 bit/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.
