How to Convert Celsius to Kelvin

How to Convert Celsius to Kelvin Celsius and Kelvin are the two most important temperature scales for scientific measurements. Fortunately, its easy to convert between them because the two scales have the same size degree.  All that is needed to convert Celsius to Kelvin is one simple step. (Note its Celsius, not Celcius, a common mis-spelling.) Celsius To Kelvin Conversion Formula Take your Celsius temperature and add 273.15. K  °C 273.15Your answer will be in Kelvin. Remember, the Kelvin temperature scale does not use the degree ( °) symbol. The reason is because Kelvin is an absolute scale, based on absolute zero, while the zero on the Celsius scale is based on the properties of water. Also, measurements given in Kelvin will always be larger numbers than in Celsius. Celsius To Kelvin Conversion Examples For example, if you want to know what 20 °C is in Kelvin: K 20 273.15   293.15 K If you want to know what -25.7 °C is in Kelvin: K -25.7 273.15, which may be rewritten as: K 273.15 - 25.7 247.45 K More Temperature Conversion Examples Its just as easy to convert Kelvin into Celsius. Another important temperature scale is the Fahrenheit scale. If you use this scale, you should be familiar with how to convert Celsius to Fahrenheit and Kelvin to Fahrenheit.
