**Definitions:**

**Celsius** (abbreviations: **C, or °C, or deg C**): also known as centigrade, is a SI metric scale and unit of measurement for temperature and used by most countries in the world. It is named with regard to the Swedish astronomer Anders Celsius (1701–1744), who developed a similar temperature scale.

**Kelvin** (abbreviations: **K, or °K, or deg K**): is a unit of measure for temperature based upon an absolute scale, thermodynamic temperature scale using as its null point absolute zero, the temperature at which all thermal motion ceases in the classical description of thermodynamics. It was first proposed in 1848 and is one of the seven base units in the International System of Units (SI).

## How to Convert Degree Celsius to Degree Kelvin

*Example: How many degree Kelvin are equivalent to 52.19 degree Celsius?*

As;

1 degree Celsius = X+273.15 degree Kelvin

52.19 degree Celsius = Y degree Kelvin

Assuming Y is the answer, and by substitution principle;

Y equals ( 52.19+273.15 ) over 1, where X is substituted by 52.19

(i.e.) Y = ( 52.19+273.15 ) / 1 = 325.34 degree Kelvin

Answer is: 325.34 degree Kelvin are equivalent to 52.19 degree Celsius.
