Convertisseur de Stockage Numérique - Décimal (Mo, Go) vs Binaire (Mio, Gio)
Convertissez les unités de stockage entre standards décimaux (SI: Mo, Go, To) et binaires (CEI: Mio, Gio, Tio) avec calcul de l'espace réel utilisable par l'OS.
Technical Metrology Standard: Storage capacity calculations comply with NIST SP 800-88, IEEE 1541-2008, and IEC 60027-2 standards. Apparent capacity variance between retail drive packaging and operating system file managers results from Base-10 (decimal 1,000) versus Base-2 (binary 1,024) addressing conventions and partition metadata overhead, not media corruption.
