Frequently asked questions

What changes between the 1024 and 1000 modes?

The 1024 mode follows binary multiples often seen in computing, while the 1000 mode uses decimal prefixes. Because the two conventions produce different numbers, use the one that matches the source you are comparing.

Can I convert from a larger unit to a smaller one?

Yes, you can go from GB to MB, TB to GB or in the opposite direction. State the source and target units clearly so you do not mix up binary and decimal results.

Does importing a file alter or keep the file?

No. Importing only provides content for the conversion step. The file itself is not changed, and the calculation runs locally in the browser without storing the file.
