What to reach out about

  • Bug reports — if a calculator gives an unexpected result or something breaks, let us know what you entered and what you expected.
  • Feature requests — missing a measurement mode, unit, or output? Tell us what you need.
  • General feedback — if the tools helped you plan a project, we'd genuinely love to hear about it.
  • Content questions — questions about the guides or installation advice.
