To convert Celsius to Kelvin, you simply add 273.15 to the Celsius temperature. The Kelvin scale is an absolute temperature scale where 0 K represents absolute zero, the point where all molecular motion stops.
For example, if you have 20°C, you can convert it to Kelvin using the formula:
K = °C + 273 K
So, for 20°C:
K = 20 + 273.15 = 293.15 K
Therefore, 20°C is equal to 293.15 Kelvin.
This conversion is essential in scientific fields, as many calculations and formulas, especially in physics and chemistry, require temperatures to be expressed in Kelvin. The Kelvin scale has no negative values, making it particularly useful for thermodynamic measurements. Understanding this simple conversion can help in understanding temperature-related phenomena in various scientific disciplines.
