The best way to reach us is by email: contact@cubedcalc.com.

We're glad to hear about:

• A calculator result that doesn't match your local building code or a manufacturer spec
• A formula, unit conversion, or worked example that looks wrong
• A calculator you'd like to see added to the site
• General feedback, or questions about how a calculator works

We're a small, independent operation, so replies may take a few days. We read every message, but can't provide project-specific engineering advice or act as a substitute for a licensed contractor, engineer, or electrician. See our Disclaimer for more on that.
