Frequently asked questions
What is the difference between KB and KiB?
KB (decimal, SI) = 1,000 bytes and is what drive makers and networks quote. KiB (binary, IEC) = 1,024 bytes and is what operating systems historically show. The tool offers both modes so you can see which answer matches your context.
Is my data uploaded?
No. Conversion is arithmetic in your browser — nothing leaves your device.
Which mode should I use?
Use Decimal (1000) for storage shopping and network speeds, Binary (1024) when matching Windows/RAM-style reporting.
