Enter the temperature value

Select the unit (Celsius, Fahrenheit, or Kelvin)

Instantly view the converted values

The conversion happens in real time with high precision.


Temperature Conversion Formulas

Celsius to Fahrenheit

°F=(°C×9/5)+32°F = (°C \times 9/5) + 32

Fahrenheit to Celsius

°C=(°F32)×5/9°C = (°F - 32) \times 5/9

Celsius to Kelvin

K=°C+273.15K = °C + 273.15

Kelvin to Celsius

°C=K273.15°C = K - 273.15

Fahrenheit to Kelvin

K=(°F32)×5/9+273.15K = (°F - 32) \times 5/9 + 273.15

The calculator automatically applies these formulas so you don’t have to.


Example Temperature Conversions
