What's the difference between KB and kB?

KB (uppercase) uses the binary system (1,024 bytes), while kB (lowercase) uses the decimal system (1,000 bytes). Most computers use the binary system.

Why do file sizes appear different on different devices?

Different operating systems and applications may use either binary (1024-based) or decimal (1000-based) calculations, leading to slight variations in displayed file sizes.

How accurate are the conversions?

Our converter uses precise mathematical calculations and displays results with appropriate decimal precision for maximum accuracy.

Can I convert any file type?

Yes! The converter works with any file type since it only reads the file size metadata, not the file content itself.
