Binary vs Decimal
Binary units (KiB, MiB, GiB) use 1024 as the conversion factor, matching how computers address memory. Decimal units (KB, MB, GB) use 1000, matching how storage manufacturers label drives. A 500 GB drive (decimal) is approximately 465 GiB (binary). The IEC standard recommends KiB/MiB/GiB for binary and KB/MB/GB for decimal to avoid confusion.
