Frequently Asked Domande

What is the difference between KB and KiB?

KB (kilobyte) uses decimal prefixes where 1 KB = 1000 bytes. KiB (kibibyte) uses binary prefixes where 1 KiB = 1024 bytes. Hard drive manufacturers typically use decimal, while operating systems often display binary sizes.

How do I convert between MB and GB?

In decimal: 1 GB = 1000 MB. In binary: 1 GiB = 1024 MiB. Simply enter the value, select the from/a units, and the tool will calculate instantly.

Why does my 1TB hard drive show less than 1TB?

Hard drive manufacturers use decimal (1 TB = 1,000,000,000,000 bytes), but operating systems often display in binary (1 TiB = 1,099,511,627,776 bytes). So a 1TB drive appears as about 931 GiB in Windows.

Can I convert very large files?

Yes. This tool supports values up a petabytes (PB) and beyond. There is no practical limit since all calculations are done locally in your browser using JavaScript.
