Convertisseur de Taille de Fichier
The file size converter is a powerful tool for converting between digital storage units. It supports both decimal (SI) units where 1 KB equals 1,000 bytes, and binary (IEC) units where 1 KiB equals 1,024 bytes.

Explication Mathématique
File size conversion involves understanding two unit systems: decimal (SI) where each step multiplies by 1,000, and binary (IEC) where each step multiplies by 1,024.
Questions Fréquemment Posées
Decimal (SI) units use base-10 (1 KB = 1,000 bytes), commonly used by manufacturers. Binary (IEC) units use base-2 (1 KiB = 1,024 bytes), used by operating systems.
Manufacturers use decimal gigabytes (1 GB = 1,000,000,000 bytes), while Windows uses binary gibibytes (1 GiB = 1,073,741,824 bytes).
In decimal (SI), 1 GB = 1,000,000,000 bytes. In binary (IEC), 1 GiB = 1,073,741,824 bytes.
Typical sizes: MP3 song (3-5 MB), photo (2-10 MB), 4K movie (15-40 GB), AAA video game (50-150 GB).
Use decimal for marketing and purchasing. Use binary for system administration and programming.
