Convert Mebibytes to Bytes
Convert Mebibytes (MiB) to Bytes (B) instantly and accurately.
Conversion Formula
B = MiB × 1048576
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.
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.
