Conversion Formula
Mibit = B × 7.629394531e-6
About Bytes
The byte (B) is the fundamental addressable memory unit - 8 bits, 256 values (0-255). Standardised by the IBM System/360 (1964). UTF-8 encodes ASCII in 1 byte; Unicode in 1-4 bytes. One byte = 1 ASCII character, 1 RGB channel value, 1 PCM audio sample (8-bit). All mainstream CPU architectures (x86-64, ARM64, RISC-V) increment addresses by 1 byte. 1 byte = 8 bits = 2 nibbles.
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.
