Client-Side Calculations
Every calculator on UnElectrica runs entirely in your browser using vanilla JavaScript. When you press Calculate, no form data is sent to any server. Your inputs never leave your device. This is a deliberate architectural choice — not a cost-cutting measure.
Mathematical Accuracy
All formulas are sourced from established standards: NEC (NFPA 70), IEEE, and IEC publications. Each calculator page documents the exact formula used, the variables, and step-by-step methodology so you can verify the math independently. We never round intermediate values — only final outputs.
No Account Required
You should not need to create an account to calculate voltage drop on a 100-ft conductor run. All tools are free, immediate, and accessible without registration. We believe paywalled engineering tools create unnecessary barriers to education and professional practice.
Focused, Crawlable Pages
Each calculator has its own dedicated URL, metadata, and structured content. This means search engines can index individual tools, and engineers can bookmark or share a specific calculator directly. We avoid hiding tools inside single-page apps that can't be indexed.
Minimal, Unobtrusive Interface
The interface surfaces the calculation — not the website. There are no pop-ups, no overlays, no "upgrade" prompts. If you came to calculate something, you should be done in under 10 seconds.
