Kelvin (K) and Celsius (°C) are both temperature scales used to measure temperature.
Kelvin
Kelvin is an absolute temperature scale. It is named after the Scottish physicist William Thomson, also known as Lord Kelvin. The Kelvin scale starts at absolute zero, which is the coldest temperature possible and is equivalent to -273.15 degrees Celsius. In the Kelvin scale, temperatures are measured in units called Kelvin (K), and they are always positive values.
Celsius
Celsius, also known as the centigrade scale, is a relative temperature scale named after the Swedish astronomer Anders Celsius. It is widely used in many parts of the world for everyday temperature measurements. On the Celsius scale, the freezing point of water is defined as 0°C, and the boiling point of water is defined as 100°C at standard atmospheric pressure.
How to convert Kelvin to Celsius
To convert from Kelvin to Celsius, you need to subtract 273.15 from the Kelvin value:
°C = K – 273.15
For example, if you have a temperature of 300 Kelvin, the equivalent temperature in Celsius would be:
°C = 300 – 273.15 = 26.85°C
To convert from Celsius to Kelvin, you need to add 273.15 to the Celsius value:
K = °C + 273.15
For Example- Convert 373 kelvin to celsius
Ans. °C = 373 – 273.15
°C = 99.85

Frequently Asked Questions on Kelvin to Celsius
How do you convert Kelvin to Celsius?
o convert Kelvin to Celsius, subtract 273.15 from the Kelvin value.
आप केल्विन को सेल्सियस में कैसे बदलते हैं?
केल्विन को सेल्सियस में बदलने के लिए, केल्विन के मान से 273.15 कम करें।
How to convert 1 K to 1 C?
It is not possible to directly convert 1 K to 1°C because the two scales have different reference points. One Kelvin is equal to one degree Celsius, but their reference points are different. To convert between the two, you need to use the formula mentioned earlier: °C = K - 273.15.
Why is 0 Celsius 273 Kelvin?
0 degrees Celsius is equal to 273.15 Kelvin. The Kelvin scale starts from absolute zero, which is the point at which all molecular motion theoretically stops. At this point, there is no heat energy. The offset of 273.15 is required to account for the different reference points of the Kelvin and Celsius scales.
Is 273 or 273.15 Kelvin?
The correct value is 273.15 Kelvin. This is because 0 degrees Celsius is equivalent to 273.15 Kelvin. Adding or subtracting 273.15 ensures the correct conversion between the two temperature scales.
What is 0 Kelvin known as?
0 Kelvin is known as absolute zero. It is the lowest possible temperature in the Kelvin scale, where all molecular motion theoretically ceases. No heat energy exists at this temperature.
