What are Kelvin and Celsius?

Kelvin (K) – According to the International System of Units, the kelvin (symbol: K) serves as the fundamental unit of thermodynamic temperature (SI). According to Boltzmann’s equation, it is the energy equivalent of water’s triple point. It is also the Kelvin scale unit whose null point (0 K) is absolute zero (-273.15°C), the temperature at which all thermal motion stops.

Celsius (°C) – A temperature unit developed from the SI (International System of Units) is the Celsius (symbol: °C). The kelvin, a SI unit of temperature, serves as the basis for its definition. A change of one degree in the Celsius scale corresponds to a change of one degree on the Kelvin scale perfectly.

Kelvin to Celsius Questions

Question 1: 

Convert 100 kelvin to Celsius


We know that the formula to convert kelvin to Celsius is: C = K – 273.15

Given that, K = 100

Now, substitute the value in the formula to get the celsius value.

Celsius, C = 100 – 273.15

C = -173.15

Therefore, 100 kelvin is equal to -173.15°C.

Question 2: 

Convert 300 kelvin to Celsius


We know that, C = K – 273.15

Given that, K = 300

Substituting the given value in the formula, we get

C = 300 – 273.15

C = 26.85

Hence, 300 kelvin is equal to 26.85°C.

Question 3:

Convert 273 kelvin to celsius


Given kelvin value, K = 273

As we know, the formula to convert kelvin to celsius is C = K – 273.15.

Therefore, C = 273 – 273.15

C = – 0.15

Therefore, 273 kelvin is equal to – 0.15°C
