About Temperature Converter
The Temperature Converter translates between Celsius, Fahrenheit and Kelvin instantly. Enter a temperature in any scale and see its equivalent in the others — ideal for weather, cooking, science homework and travel.
Unlike simple unit converters, temperature scales don't share a common zero, so the tool applies the proper formulas: °F = °C × 9/5 + 32 and K = °C + 273.15. Negative values and decimals are fully supported.
The conversion happens as you type, entirely in your browser.
