Temperature Converter: Convert Between Celsius, Fahrenheit, and Kelvin

Temperature scales vary by country and application. The US uses Fahrenheit for weather, most of the world uses Celsius, and scientists use Kelvin. Our Temperature Converter instantly converts between all three scales with the conversion formulas displayed. Whether you are cooking an international recipe, checking weather forecasts, or solving a science problem, get accurate temperature conversions.

Conversion formulas: °C = (°F - 32) × 5/9. °F = (°C × 9/5) + 32. K = °C + 273.15. Key reference points: water freezes at 0°C / 32°F / 273.15 K. Water boils at 100°C / 212°F / 373.15 K. Room temperature is about 20°C / 68°F. Body temperature is 37°C / 98.6°F.

Use the Temperature Converter for international recipes (convert oven temperatures between °C and °F), weather understanding (what is 25°C in °F?), science and lab work (Celsius to Kelvin for gas law calculations), and travel preparation (packing for a destination with a different temperature scale).
