About QConvert

QConvert is a free, fast online tool for converting between metric, imperial, and engineering units. Built for accuracy and speed, every page uses internationally recognized conversion factors (SI / BIPM) and only a tiny converter widget loads on the client — everything else is static HTML.

What we cover

• Everyday units: length, mass, temperature, volume, area, speed
• Engineering units: pressure/stress, force, torque, density, flow rate, power, energy
• Exact factors; temperature uses proper offset formulas (Celsius ⇄ Fahrenheit, Kelvin, Rankine)

Performance & privacy

No accounts, no tracking cookies, no database. Pages render instantly and only the converter widget hydrates client-side.
