The basic terms for using ElectroCalc's calculators and website.
By accessing or using ElectroCalc (electrocalc.in), you agree to these Terms of Service. If you don't agree, please don't use the site. We may update these terms occasionally; continued use after changes means you accept the revised terms.
ElectroCalc offers free, browser-based electrical and electronics calculators — including resistor color code decoding, Ohm's Law solving, wire gauge sizing, and related tools. All calculators run client-side in your browser; no account or signup is required.
All calculators on ElectroCalc are free to use, with no signup, subscription, or payment required. The site is supported by advertising (Google AdSense) to keep it free. See our Disclaimer for important limitations on how calculator results should be used.
You agree not to:
The design, code, and original written content on ElectroCalc are owned by ElectroCalc. The underlying formulas and engineering standards used (Ohm's Law, AWG tables, IPC-2221, EIA color codes, etc.) are publicly available industry standards and not proprietary to us.
ElectroCalc uses Google Analytics, Google AdSense, and Giscus (GitHub-based comments). Your use of these integrated features is also subject to those providers' own terms — see our Privacy Policy for details.
ElectroCalc is provided "as is" without warranties of any kind. Calculator results are for reference and educational purposes only — see our full Disclaimer for important details, especially regarding electrical safety calculations. We are not liable for damages arising from use of this site or reliance on its calculators.
We may add, modify, or remove calculators and features at any time without notice, as this is an actively developed project.
