What is UnElectrica?
We created UnElectrica to make everyday electrical engineering calculations faster and more trustworthy. Whether you are sizing a cable run, checking voltage drop on a feeder, calculating motor full-load amperes, or correcting power factor — the goal is the same: give you an accurate result quickly and explain the engineering behind it.
Our Principles
- Accuracy first: All calculators use standard NEC, IEEE, and IEC formulas with clear labels so you know exactly what each result means.
- Privacy by design: Calculations run entirely in your browser. No data is sent to any server.
- Simple access: Every tool has its own dedicated page — fast to find, fast to load, and easy to share.
- No account required: All calculators are completely free with no paywalls or sign-up walls.
What makes UnElectrica different?
The calculators are designed as focused, crawlable pages so search engines and engineers can find the exact tool they need instantly. Instead of a single slow-loading app, each major calculator has its own route, metadata, formula documentation, and worked examples. We keep the interface minimal and unobtrusive so you can focus on the calculation.
A Sister Site of UnCalculator
UnElectrica is a sister site of UnCalculator.com— a broader free calculator platform covering finance, health, date & time, and math tools. Both platforms share the same philosophy: fast, private, client-side calculations with no account needed.
Pankaj P. Patel is the Founder and Developer of UnElectrica and UnCalculator. He leads the architecture, calculator engineering, and technical development — ensuring all calculators run client-side, fast, private, and fully accessible.
