Terms of Use

By using electrical.nowcalculator.net (the "Site") you agree to these terms. If you do not agree, please do not use the Site.

1. What the Site provides

The Site offers free, browser-based electrical and networking calculators — including an Ohm's Law calculator, a voltage drop calculator, a BTU/AC sizing calculator, a resistor colour-code calculator, a bandwidth/download-time calculator, and an IP subnet calculator — along with related educational content. All calculations are performed within your browser; the figures you enter are not transmitted to or stored on our servers.

2. Not professional advice

The Site provides tools and general information for educational purposes only. It does not provide professional electrical, engineering or safety advice, and no professional relationship is created by using it. Electrical work can be dangerous and is governed by local codes. Always follow your local electrical code and, for any real installation, consult a licensed electrician or qualified engineer.

3. Accuracy and limitations

Our calculators use standard formulas and reasonable assumptions, but results are estimates. They may not reflect real-world conditions, temperature, code requirements, equipment tolerances, or site-specific factors. Reference information and energy statistics may become out of date; verify current details at the source. Use all results at your own discretion and never as a substitute for a qualified professional.

4. Acceptable use

You may use our calculators freely for personal and commercial purposes. You may not copy, scrape, republish, or resell our written content or calculator code without permission.

5. Third-party links

The Site links to external websites, such as banks, scholarship programs and credit bureaus, for your convenience. We do not control and are not responsible for their content, offers, or practices.

6. Availability

We may change, add, or remove calculators and content at any time, and the Site may occasionally be unavailable for maintenance.

7. Limitation of liability

To the fullest extent permitted by law, NowCalculator is not liable for any loss or damage arising from your use of, or reliance on, this Site or any third party it links to.

8. Changes

We may update these terms from time to time. Continued use of the Site means you accept the current version.

9. Contact
