Temperature Converter

Is 68 °F warm or cold? What oven setting is 350 °F in Celsius? And why do physics formulas insist on Kelvin? This temperature converter translates between Celsius, Fahrenheit and Kelvin as you type, and always shows the exact formula it applied.

Temperature is trickier than most units because the scales disagree about where zero is: converting is not a single multiplication. The tool applies the exact defined relations — °F = °C × 9/5 + 32, K = °C + 273.15, and their inverses — with clean rounding for display, so 37 °C is 98.6 °F, not 98.60000000000001.

Everything happens locally in your browser: no data sent anywhere, no sign-up, and the page works offline once loaded. Both fields are live and stay in sync in either direction, the swap button flips the scales in one click, and a reference table under the result lists everyday anchors — freezing and boiling points, room and body temperature, common oven settings.

Typical users include travelers decoding foreign weather forecasts, cooks following American recipes, students doing physics and chemistry homework, aquarium and 3D-printer owners checking equipment settings, and anyone who just wants to know whether to bring a jacket.
