Celsius to Kelvins Conversion
Enter the temperature in Celsius below to get the value converted to kelvins.
How to Convert Celsius to Kelvins
Convert degrees Celsius to kelvins with this simple formula:
The formula to convert Celsius to kelvins is °C plus 273.15. Insert the [°C] temperature measurement in the formula and then solve to find the result.
For example, let's convert 50 °C to kelvins:
50 °C = ( 50 + 273.15 ) = 323.15 K
The Celsius scale and Kelvins are both used to measure temperature. Read on to learn more about each of them.
The Celsius temperature scale, also commonly referred to as the centigrade scale, is defined in relation to the kelvin. Specifically, degrees Celsius is equal to kelvins minus 273.15.
The degree Celsius is the SI derived unit for temperature in the metric system. A degree Celsius is sometimes also referred to as a degree centigrade. Celsius can be abbreviated as C; for example, 1 degree Celsius can be written as 1 °C.
Important Temperatures In Degrees Celsius
|Absolute Zero||-273.15 °C|
|Freezing Point of Water||0 °C|
|Triple Point of Water||0.01 °C|
|Boiling Point of Water||100 °C|
The Kelvin scale is an absolute temperature scale that uses absolute zero as the starting point. The kelvin is defined in terms of the Boltzmann constant, which is a measure of the energy of motion corresponding to one kelvin.
More specifically, one kelvin is equal to the change of thermodynamic temperature that results in a change of thermal energy kT by 1.380649 × 10−23 J.
0 kelvins are equal to −273.15 degrees Celsius, which is the point of absolute zero.
The kelvin is the SI base unit for temperature in the metric system. Kelvins can be abbreviated as K; for example, 1 kelvin can be written as 1 K.
The kelvin scale is different from other temperature scales in that it is not expressed in degrees, values are expressed in kelvins. When using the Kelvin scale in writing, the "k" is capitalized, however when using the kelvin as a unit the "k" should be lower-case, even though it is named for a person.
