Conversion Formula
MiB = Mibit × 0.125
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 Mebibytes
A mebibyte (MiB) = 2²⁰ = 1,048,576 bytes (IEC 80000-13). Windows/older macOS report sizes in MiB but label them 'MB'. Linux malloc and kernel pages are power-of-2 aligned. Docker images: Alpine base 5 MiB; Ubuntu 72 MiB. Linux kernel bzImage 8-12 MiB. NVIDIA RTX 4090: 24 GiB GDDR6X in 2-GiB binary chunks. 1 MiB = 1,048,576 bytes = 1,024 KiB.
