About Megabytes
A megabyte (MB) = 1,000,000 bytes (SI). Used by all storage manufacturers and by macOS (since 10.6), iOS, and Android. Typical file sizes: JPEG photo (50 MP) = 8-20 MB; 3-min MP3 at 128 kbit/s ≈ 2.9 MB; Android productivity APK 10-150 MB; full-frame RAW photo (Sony A7R V, 61 MP) 60-120 MB. H.264/H.265 achieves 30-100× compression vs. raw video. 1 MB = 1,000,000 bytes = 1,000 KB.
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.
