Convert Kibibytes per second to Gigabytes per second
Convert Kibibytes per second (KiB/s) to Gigabytes per second (GB/s) instantly and accurately.
Conversion Formula
GB/s = KiB/s × 1.024000000e-6
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 Gigabytes per second
Gigabyte per second (GB/s) = 10⁹ B/s (SI). Dominant unit for memory bandwidth and GPU interconnects. DRAM: Intel i9-13900K DDR5 = 89.6 GB/s; AMD EPYC Genoa 8-channel = 460.8 GB/s. H100 HBM3 = 3,350 GB/s; RTX 4090 GDDR6X = 1,008 GB/s. PCIe 5.0 ×16 = 128 GB/s. HPC Lustre on Frontier ≈ 5,000 GB/s aggregate. 100 Gbit/s Ethernet = 12.5 GB/s. 1 GB/s = 10⁹ B/s = 8 Gbit/s.
