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.
À Propos des Unités Binaires vs Décimales
Il existe deux systèmes pour mesurer la taille des fichiers : décimal (SI) et binaire (IEC). Le décimal utilise des puissances de 1000, tandis que le binaire utilise des puissances de 1024. C'est pourquoi un disque dur de 500 Go s'affiche comme 465 Gio dans votre système d'exploitation.
Exemple : 1 Go (décimal) = 1 000 000 000 octets, mais 1 Gio (binaire) = 1 073 741 824 octets

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.
