30 °C |
30 + 273.15 |
303.15 K |
40 °C |
40 + 273.15 |
313.15 K |
How to Convert °C to K
- Identify the Temperature in Celsius: For example, 25 °C.
- Apply the Conversion Formula:
- Simply add 273.15 to the Celsius temperature.
- For 25 °C:
- Calculation: 25 + 273.15 = 298.15 K
Practical Uses
- Scientific Calculations: Kelvin is the standard unit for temperature in scientific studies, particularly in fields like physics and chemistry.
- Thermodynamics: Kelvin is crucial for calculations involving absolute temperatures, such as in thermodynamics.
Summary
To convert degrees Celsius to Kelvin, simply add 273.15 to the Celsius value. For example, 20 °C is approximately 293.15 K, and 40 °C is about 313.15 K. This conversion is commonly used in scientific contexts where absolute temperature is needed.
