Temperature Unit Converter
Convert between Celsius, Fahrenheit, Kelvin, Rankine, Rømer, Delisle, Réaumur, and Newton.
Enter a temperature in any unit and the converter will automatically calculate the values in all other units.
What is the Temperature Unit Converter?
The Temperature Unit Converter allows you to convert temperatures between eight different scales including Celsius, Fahrenheit, Kelvin, Rankine, Delisle, Newton, Réaumur, and Rømer. Enter a temperature in any unit and the converter will automatically calculate the corresponding values in all other units.
Conversion Formulas
Below are the core formulas used for converting between temperature scales. Many conversions work by first converting to Celsius and then to the target unit:
°C = (°F − 32) × 5/9
K = °C + 273.15
°R = K × 9/5
°Ré = °C × 4/5
°De = (100 − °C) × 3/2
°N = °C × 33/100
°Rø = (°C × 21/40) + 7.5
These formulas allow conversion from one temperature unit to any other by intermediate steps (e.g., convert to Celsius first, then to the desired scale).
How It Works
- Enter a Temperature:
Input a temperature value in any supported unit. - Automatic Conversion:
The tool uses standard formulas internally to compute equivalent values in all other units. - Instant Results:
Converted values are displayed immediately in all supported temperature scales.
