About this tool
Temperature Converter is a free online converter. Convert between Celsius, Fahrenheit and Kelvin. Convert files and values in just a few seconds. It runs entirely in your browser — no download or sign-up needed.
Enter a temperature value and select units (degrees Celsius °C, degrees Fahrenheit °F, Kelvin K), and the tool will display the corresponding values of the other two units in real time. For example, entering 25°C will display 77°F and 298.15K. Supports decimal input, and retains appropriate precision for results.
Conversion formula: °F = °C × 9/5 + 32, K = °C + 273.15. The three units can be converted to each other, and the tool will automatically apply the correct formula. Absolute zero (-273.15 ° C/ 0K / -459.67 ° F) is the theoretical minimum temperature.
It is suitable for understanding local temperatures while traveling, converting oven temperatures while cooking, or verifying temperature conversions while learning thermodynamics. Faster than looking up a table.
Temperature conversion tool converts between degrees Celsius, degrees Fahrenheit, and Kelvin, and supports inputting any temperature to display values in other units in real time.
