How to convert Celsius to Kelvin

The relationship between temperature in Celsius (ToC) and temperature in Kelvin (TK) is given below:

ToC = TK - 273.15

Alternatively, it can also be written as:

ToC + 273.15 = TK

TK - ToC = 273.15


Example

To convert 100 Celsius into Kelvin, 273.15 is added to it:

(100 oC) + 273.15 = 373.15 K

Celsius

The degree Celsius is a unit of temperature on the Celsius scale. The degree Celsius (symbol: oC) refers to a specific temperature on the Celsius scale or a unit to indicate a difference between two temperatures. Since 1743 the Celsius scale has been based on 0 oC for the freezing point of water and 100 oC for the boiling point of water at 1 atm pressure.

Kelvin

The Kelvin is the base unit of temperature in the International System of Units (SI), having the unit symbol K. It uses absolute zero as its null point. On the Kelvin scale, pure water freezes at 273.15 K, and it boils at 373.15 K.
