Celsius is the standard in most countries and everyday life. Fahrenheit is used in the US, so conversion is handy when reading American recipes (an oven at 350 °F ≈ 177 °C), weather forecasts, or instructions. Kelvin is the scientific scale, where 0 K is absolute zero (−273.15 °C); it's used in physics and to describe the color temperature of lighting.

Conversion formulas: °F = °C × 9/5 + 32; K = °C + 273.15. Useful reference points: 0 °C = 32 °F (water freezes), 100 °C = 212 °F (water boils), a comfortable 20 °C = 68 °F, and body temperature 37 °C ≈ 98.6 °F. Calculations run right in your browser, instantly, with no data sent anywhere.
