Here you can convert the Temperature Unit Celsius into the unit Kelvin and vice versa you can convert Kelvin into Celsius. By clicking the "Swap units" icon, you will always obtain the desired conversion in the calculation result, i.e., °C to K or K to °C. With the following calculator you can also calculate any other Temperature Unit.
Info about "Celsius"
The common unit for temperature in German-speaking countries is measured in degree Celsius (°C). Anders Celsius, a Swedish astronomer, mathematician and physicist, defined this temperature division named after him, degree Celsius, in the 18th century.
He chose the melting point and boiling point of water as fixed points for the temperature scale and divided the change in volume of mercury between these points into 100 equal parts. So today we are used to water freezing at 0 degree Celsius and water boiling at 100 degrees Celsius. And to measure the temperature, mercury thermometers are often still in use.
Celsius thus forms a so-called empirical temperature scale, i.e., an arbitrary determination of the magnitude of the temperature by indicating the temperature in relation to a reference value. For degree Celsius, the arbitrary determination, as described, is between 0 degree and 100 degrees, depending on the aggregate state of the water.
While Kelvin is the base unit for temperature in the international system of units SI (Système international d'unités), degree Celsius (°C) is an officially derived SI unit. As a derived SI unit, the degree Celsius (°C) is officially approved in many European countries, especially in Germany, Austria and Switzerland.
