About

Free Temperature Converter helps you convert between Celsius, Fahrenheit, Kelvin, Rankine, and Réaumur with instant, bidirectional results - entirely in your browser.

Why we built it

Most converter sites are cluttered, slow, or require clicking Convert for every change. We wanted a single-purpose tool that feels as immediate as measuring with a ruler: type a value, read every scale, share the link.

How it works

All math runs client-side. Conversions pass through Kelvin at full precision before display rounding. No accounts, no ads, no tracking beyond basic analytics you control at deploy time.
