How to Convert Kelvin to Celsius with Formula and Examples

Kelvin to Celsius Calculator

What is Kelvin to Celsius Calculator?

The Kelvin to Celsius Calculator is a simple online tool that instantly converts temperatures from the Kelvin scale (K) to the Celsius scale (°C). Kelvin is often used in scientific calculations, while Celsius is common in daily life and classrooms. This calculator ensures quick, accurate conversion within seconds.


Students, teachers, and professionals frequently need to convert from Kelvin to Celsius for physics, chemistry, laboratory work, weather reports, and competitive exams. Instead of manual calculations, you can get the answer in one click with this tool.


Formula or Logic Behind Kelvin to Celsius Calculator

The relationship between Kelvin and Celsius is straightforward. The Celsius scale is offset from Kelvin by exactly 273.15 degrees. The formula is:


Celsius (°C) = Kelvin (K) - 273.15


For example, if you have 300K, subtract 273.15 to get 26.85°C. This conversion is widely used in class 9, 10, and competitive science exams, as well as physics practicals.

FAQs on Kelvin to Celsius Calculator Online

1. How do you convert Kelvin to Celsius?

To convert Kelvin to Celsius, simply subtract 273.15 from the Kelvin temperature. This is because 0°C is equivalent to 273.15 K. The formula is: Celsius = Kelvin - 273.15

2. What is the formula for converting Kelvin to Celsius?

The formula for converting Kelvin to Celsius is: Celsius = Kelvin - 273.15. This formula is universally applicable for all Kelvin temperature conversions.

3. What is 273 Kelvin in Celsius?

Using the formula Celsius = Kelvin - 273.15, 273 Kelvin is equal to 0°C. This is the freezing point of water.

4. How can I convert 293K into the Celsius scale?

To convert 293K to Celsius, subtract 273.15: 293 - 273.15 = 19.85°C

5. How to convert Kelvin to Celsius quickly?

The quickest way is to use an online Kelvin to Celsius calculator. Alternatively, use the formula: Celsius = Kelvin - 273.15

6. What is the difference between Kelvin and Celsius?

Kelvin and Celsius are both temperature scales. The main difference is the starting point: 0 Kelvin (0K) represents absolute zero, the lowest possible temperature, while 0° Celsius (0°C) is the freezing point of water. Kelvin uses absolute units, while Celsius uses relative units.

7. Why is it important to know how to convert Kelvin to Celsius?

Knowing how to convert between Kelvin and Celsius is crucial in various scientific fields, including physics, chemistry, and meteorology. Many scientific formulas require temperature to be in Kelvin, while everyday applications use Celsius. The ability to convert ensures accurate calculations and understanding across disciplines.

8. Convert 100 Kelvin to Celsius.

100 Kelvin - 273.15 = -173.15°C

9. What are some real-world applications of Kelvin to Celsius conversion?

Real-world applications include:
  • Scientific experiments: Many experiments require temperature readings in Kelvin.
  • Meteorology: Weather reports often use Celsius, but meteorological calculations might use Kelvin.
  • Engineering: Various engineering calculations necessitate temperature conversions.

10. Is there an easy way to remember the Kelvin to Celsius conversion?

Yes! Remember that 0°C is 273.15K. To convert Kelvin to Celsius, simply subtract 273.15. This simple subtraction makes the conversion straightforward.

11. How accurate is the Kelvin to Celsius conversion formula?
