Convert between Celsius, Fahrenheit and Kelvin
Our temperature converter is a professional and precise tool that allows instant conversions between the three main temperature scales: Celsius (°C), Fahrenheit (°F), and Kelvin (K). Perfect for students, scientists, cooks, travelers, and professionals who need quick and accurate temperature conversions in different contexts, from international cooking recipes to complex scientific calculations and weather analyses.
Our converter uses international standard mathematical formulas to ensure precise conversions between all temperature scales:
Enter the temperature value you want to convert in the main numeric field.
Select the source temperature scale (Celsius, Fahrenheit, or Kelvin) from the 'From' dropdown menu.
Choose the target temperature scale in the 'To' menu and the conversion is performed automatically and instantly.
Copy the result with one click to use in your calculations, documents, or applications.
This tool is essential in multiple professional and everyday contexts:
Students and scientists conducting experiments who need to convert temperatures between scales for data analysis and scientific reports.
Cooks and chefs following international recipes who must convert between Celsius and Fahrenheit for oven temperatures.
Travelers visiting countries with different measurement systems who need to understand local weather forecasts.
Engineers and technicians working with international specifications who require precise conversions for equipment and industrial processes.
For cooking: 180°C is approximately 350°F, a common temperature for baking.
Absolute zero is 0 Kelvin, equivalent to -273.15°C or -459.67°F, the theoretically lowest possible temperature.
The freezing point of water is 0°C, 32°F, or 273.15 K, while its boiling point is 100°C, 212°F, or 373.15 K.
Celsius is mainly used in metric countries and science, Fahrenheit in the United States, and Kelvin is the SI unit used in science. Kelvin doesn't use the degree symbol (°) and starts at absolute zero.
They are different scales with distinct reference points. 0°C is the freezing point of water, while 0°F was established by Fahrenheit using a mixture of ice, water, and salt.
A quick approximation is to multiply Celsius by 2 and add 30. The exact formula is (°C × 9/5) + 32 = °F. For example, 20°C × 2 + 30 ≈ 70°F (exact: 68°F).
