Binary vs Decimal Systems
Understanding the difference between computer storage and marketing measurements

Binary System (Computer)

1 KB =1,024 bytes
1 MB =1,024 KB
1 GB =1,024 MB
Used by operating systems and file systems for actual storage capacity

Decimal System (Marketing)

1 KB =1,000 bytes
1 MB =1,000 KB
1 GB =1,000 MB
Used by manufacturers for marketing and packaging

💡 This converter uses the binary system (1024-based) which is correct for computer storage calculations. Hard drive manufacturers use decimal (1000-based) for marketing, which is why your drive may show less capacity than advertised.
