Fahrenheit to Kelvin: K = 5/9 (F - 32) + 273.15. Remember to report Celsius and Fahrenheit values in degrees. There is no degree using the Kelvin scale. This is because Celsius and Fahrenheit are relative scales.

Witryna20 gru 2013 · The main claim of such experiments is that they are able to produce systems with negative absolute temperatures, or temperatures below 0 degrees Kelvin.
