How this tool works
SI factors and named US/Imperial units are explicit. Storage distinguishes decimal MB from binary MiB. Time uses fixed durations; months and years belong in calendar tools. Currency exchange requires current rates and is not included. For batch conversion, enter up to 500 numeric lines without thousands separators. Batch output is CSV with the selected precision; single-value results keep up to 13 significant digits.
Inputs and results stay in this page’s memory until you leave or reset it. Downloads remain on your device. Review the result before using it in another application.
