Convert Megabytes per second to Kibibytes per second
Convert Megabytes per second (MB/s) to Kibibytes per second (KiB/s) instantly and accurately.
Conversion Formula
KiB/s = MB/s × 976.5625
About Megabytes per second
Megabyte per second (MB/s) = 10⁶ B/s (SI). Standard for storage benchmarks and USB speeds. NVMe SSDs: Samsung 990 Pro (PCIe 4.0) = 7,450 MB/s; PCIe 5.0 drives = 10,000 MB/s; SATA HDD = 80-220 MB/s. USB 3.2 Gen 1 = 625 MB/s; USB4 Gen 3 = 5,000 MB/s. Memory: DDR5-4800 dual-channel = 76,800 MB/s. A 4K RAW cinema camera generates ≈1,000 MB/s. 1 MB/s = 10⁶ B/s = 8 Mbit/s.
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.
