About Funkcia

Funkcia is a collection of 68 free online calculators covering everyday math, electrical engineering, physics, mechanical engineering, finance, unit conversion, and statistics. Every tool runs instantly in your browser with no account, no paywall, and no data leaving your device.

Why Funkcia Exists

Most calculation needs do not require heavy software. Funkcia provides single-purpose tools that load fast, show the underlying formula, and give a clear result. Each page includes the relevant equations, a worked example, and notes on limitations so the tool also serves as a quick reference.

How It Works

All calculators are implemented in client-side JavaScript. Inputs you enter are computed locally and are never sent to a server. The Site is intentionally lightweight, with no tracking frameworks beyond the advertising described in our Privacy Policy.

Accuracy

Formulas are based on standard, published relationships in each field. Results are provided for educational and informational use. See our Terms & Disclaimer for the limits of intended use.
