Convert Mebibits to Kibibytes
Convert Mebibits (Mibit) to Kibibytes (KiB) instantly and accurately.
Conversion Formula
KiB = Mibit × 128
About Mebibits
A mebibit (Mibit) = 2²⁰ = 1,048,576 bits (IEC 80000-13). Used in JEDEC DRAM die specs (DDR5 16-Gibit die = 2 GiB) and FPGA block RAM. NVIDIA Ampere SM: 128 KiB = 1 Mibit of L1 cache/shared memory per SM. STM32H7 Cortex-M7: 1 Mibit tightly coupled data RAM. The 6502 (Apple II, C64) addressed 512 Kibit = 64 KiB of RAM. 1 Mibit = 1,048,576 bits = 128 KiB.
About Kibibytes
A kibibyte (KiB) = 2¹⁰ = 1,024 bytes (IEC 80000-13) - the binary kilobyte used by OS memory management. Linux/Windows page size = 4 KiB (4,096 bytes); default NTFS/ext4/APFS cluster size = 4 KiB. CPU L1-D cache: 16-64 KiB. Arduino AVR flash: 2-32 KiB. Windows labels KiB as 'KB'. 1 KiB = 1,024 bytes = 8,192 bits.
