Frequently asked questions
Is my input uploaded?
No. This tool processes its input locally in your browser. Normal page requests do not include the contents you enter or select.
Why can a result show more digits than expected?
Conversion constants can produce repeating decimals. Use the precision control to show meaningful digits without implying measurement accuracy you do not have.
Will it work in every browser?
The tool uses modern browser APIs. Current Chromium, Firefox, and Safari releases provide the best support; the page displays a clear error when a required capability is unavailable.
