What is Kelvin to Celsius?
Kelvin and Celsius are the two scales in which temperature is measured. Sometimes we need to convert the temperature from the Kelvin scale to the Celsius scale. This term is usually referred to as 'Kelvin to Celsius'.
What is Kelvin?
Kelvin is the base unit to measure temperature in the International System of Units, also known as the SI unit. It is denoted by the symbol K. It should be noted that we do not use 'degree' in the Kelvin scale because it is an absolute scale.
What is Celsius?
Celsius is a unit for measuring temperature in which water freezes at 0° and boils at 100° under standard conditions. It is denoted by the letter C. The Celsius scale is split into 100 equal divisions called degrees. This scale is also called the Centigrade scale since there are 100 degrees between the two points.
Relationship Between Kelvin and Celsius
The relationship between the Kelvin scale and the Celsius scale is expressed as, 0 Kelvin = 273.15° Celsius. This means that 0 Kelvin is equal to 273.15 degrees Celsius. The following figure shows the relationship between the Kelvin scale and the Celsius scale.
Kelvin to Celsius Formula
The Kelvin to Celsius formula (K to C formula) which is used to convert the given temperature from Kelvin to Celsius is expressed as:
Celsius = Kelvin  273.15°
This means if a temperature is given in Kelvin, it can be converted to Celsius by substituting the value of Kelvin in the given formula. Let us understand the Kelvin to Celsius conversion in the following section.
Kelvin to Celsius Conversion
Kelvin to Celsius conversion can be easily done using the K to C formula. Let us understand these with the help of a few examples.
Example: Convert 300 Kelvin to Celsius.
Solution: Let us use the Kelvin to Celsius formula, Celsius = Kelvin  273.15°. Substituting the value of Kelvin as 300, we get, Celsius = 300  273.15° = 26.85°C.
Example: Convert 400 Kelvin to Celsius.
Solution: To convert 400 Kelvin to Celsius, we will use the K to C formula, Celsius = Kelvin  273.15°. After substituting the value of Kelvin as 400, we get, Celsius = 400  273.15° = 126.85°C
