What to include

Contact [email protected]. Include the exact page URL, unit standard (for example US or Imperial), your input value, output displayed and the result you believe correct. If possible, link to a NIST, BIPM or manufacturer source supporting the correction.

How a report is reviewed

The calculation is reproduced using the stated formula and unit factors. We check whether the disagreement is due to rounding, a selected variant, a density assumption or a genuine error. We correct confirmed issues and update relevant references or examples.

Editorial transparency

Content maintenance is performed under the named author Qudoos. No guaranteed response time or independently certified review process is claimed. Every report receives consideration subject to availability.

Reporting broken layouts

If your phone, browser or keyboard makes a control difficult to use, provide a device/browser description and a screenshot if available. Avoid including private information in the report.
