Contact HardHatMath
Corrections, bug reports, tool requests — all welcome. HardHatMath is an independent project, so your message goes straight to the people who build the calculators.
[email protected] — we read every message and usually reply within a few days.
Reporting a wrong result
If a number looks off, we want to know. The fastest route is the "Spotted an error?" form at the bottom of every calculator page — it sends the report with the tool already identified. By email, include the calculator name, the exact inputs you used, the result you got, and what you expected. A pointer to the NEC section or published table you checked against helps us fix it same-day.
Requesting a calculator
Missing a tool you reach for on the job? Tell us what it should compute and which code section or published table it should follow. Tools built on public, citable sources go to the front of the queue — that's the standard every calculator here has to meet.
