Celsius to Kelvin
To convert Celsius to Kelvin we use the formula T (K) = T (°C) + 273.15. Both these temperature units are very different from each other. The Celsius scale was invented by Anders Celsius and the temperature in Celsius is represented in °C. Kelvin scale was invented by Lord Kelvin and the temperature in Kelvin is represented in K. Let us learn more about Celsius, Kelvin, C to K, C to K formula, and solve a few examples.

What is Celsius to Kelvin?
Celsius and Kelvin are considered the two most important temperature scales for measurements. To convert the same temperature from C to K we use a simple formula. Celsius is a common System International (SI) temperature scale whereas the official scale is Kelvin. The main difference between both scales is the zero point. The zero point on the kelvin scale is the theoretical temperature of no further heat loss, which is absolute zero. When C to K is converted, the Kelvin measurement will be larger than the Celsius measurement.
Definition of Celsius
Celsius is the unit of temperature seen on a Celsius scale or the centigrade scale. It can refer to specific temperatures or show a difference between two temperatures and is written as °C. The Celsius scale is split into 100 equal divisions called degrees. It also helps in measuring the boiling point of water and freezing point of water at 100° and 0° respectively.
Definition of Kelvin
Kelvin is the base unit to measure temperature in the International System of Units. The fraction 1/273.16 of the thermodynamic temperature represents the triple point of water and this scale is known as Kelvin. It divides the interval between the points of ice and steam into 100 divisions making one Kelvin the same as one Celsius. This unit is represented as K without the symbol (°) as it is an absolute scale based on absolute zero.
Celsius To Kelvin Formula
The Celsius to Kelvin formula is used to change the unit of temperature from C to K. There is actually nothing much that is complicated about this formula. The temperature can be converted from Celcius to Kelvin just by adding the number 273.15 to it. In other words, temperature T in Kelvin (K) is equal to the temperature T in degrees Celsius (°C) plus 273.15. Here is the C to K formula.
Where,
 T(°C) = Temperature in Celsius
 T (K) = Temperature in Kelvin
Celsius To Kelvin Formula Derivation
Let us observe the freezing point and the boiling point of water in both Celsius and Kelvin scales.
Celsius Scale  Kelvin Scale  

Freezing point  0°C  273.15 K 
Boiling point  100°C  373.15 K 
If we observe, each temperature in the Kelvin scale is exactly 273.15 more than the corresponding temperature in the Celsius scale. Thus, the temperature in Kelvin is obtained by adding 273.15 to the corresponding temperature in the Celsius scale. Thus, if T(°C) is the temperature in Celsius and T (K) is the temperature in Kelvin then the Celsius to Kelvin formula is,
T (K) = T (°C) + 273.15

Examples Using Celsius To Kelvin

Example 1: Convert 15°C into Kelvin.
Solution:
T(°C) = 15°C (Given)
T(K) =?
By using the Celsius to Kelvin formula,
T (K) = T (°C) + 273.15
T (K) = 15 + 273.15 = 288.15 K
15°C = 288.15 K.

Example 2: We know that the boiling point of water is 100°C. Can you convert it into Kelvin?
Solution:
T(°C) = 100°C (Given)
T(K) = ?
By using the Celsius to Kelvin formula,
T (K) = T (°C) + 273.15
T (k) = 100 + 273.15 = 373.15 K
The boiling point of water (100°C) = 373.15 K.

Example 3: If the temperature of a pizza that is in the oven is 520 K, then what is its temperature in Celsius?
Solution:
T (K) = 520 K (Given)
T(°C) =?
By using the Celsius to Kelvin formula,
T (K) = T (°C) + 273.15
520 = T (°C) + 273.15
Subtracting 273.15 from both sides,
T (°C) = 246.85
The temperature of pizza in Celsius is 246.85°C.
FAQs on Celsius To Kelvin
What is Celsius To Kelvin Formula?
The Celsius to Kelvin Formula is used to convert the temperature from C to K. This formula says T (K) = T (°C) + 273.15 where T(°C) is the temperature in Celsius and T (K) is the temperature in the Kelvin.
How To Derive the Celsius To Kelvin Formula?
If we observe any temperature in terms of Celsius and Kelvin (for example, the boiling point of water in Celsius and Kelvin is 100°C and 373.15 K respectively), the temperature in Celsius is obtained by adding 273.15 to the temperature in Kelvin. Thus, the Celsius to Kelvin formula is, T (K) = T (°C) + 273.15 where
 T(°C) is the temperature in Celsius
 T (K) is the temperature in Kelvin
What Are the Applications of Celsius To Kelvin Formula?
The Celsius to Kelvin formula, as its name suggests, is used to convert the temperature in Celsius to the temperature in Kelvin. Thus, it is widely used in the fields of Math, Physics, and Chemistry.
What is Zero Degree Celsius in Kelvin Using Celsius To Kelvin Formula?
According to the Celsius to Kelvin formula, by adding 273.15, the temperature in Celsius can be converted to the temperature in Kelvin. Thus, 0°C = 0 + 273.15 = 273.15 K.
Do You Convert Celsius To Kelvin?
Yes, we do convert C to K when the Celsius temperature is not satisfactory and we require a large number. Conversion between the two temperatures can be done by using the Celsius to Kelvin formula i.e. T (K) = T (°C) + 273.15.
