Help & answers

Frequently Asked Questions

How accurate are the conversions?

Conversions use standard, well-documented formulas and constants. For scientific or regulatory work, cross-check critical values against an authoritative reference.

Does the converter work offline once the page is loaded?

The conversion math runs in your browser, so it keeps working without a network connection as long as the page is already open.

Can I convert in both directions?

Yes. Unit and format converters on Alexonic are bidirectional — swap the source and target to reverse the conversion instantly.

Is there a limit to how many values I can convert at once?

Single-value conversions have no practical limit. For bulk/batch conversion needs, check whether the specific tool has a list or file-based mode.
