How do you convert Kelvin to Fahrenheit?

By combining two formulas.

##""^@ "F" = 9/5("K") - 459.67##

Normally, we consider ##""^@ "C"## going to ##"K"## or the other way around:

##""^@ "C" + 273.15 = "K"##

##""^@ "F" = 9/5(""^@ "C") + 32##

You could use both formulas to do the conversion, or you could substitute one into the other and derive a new formula.

Since ##"K" - 273.15 = ""^@ "C"##:

##""^@ "F" = 9/5("K" - 273.15) + 32##

With some simplification, we obtain the conversion formula from ##"K"## to ##""^@ "F"##:

##color(blue)(""^@ "F" = 9/5("K") - 459.67)##

Notice that this looks similar to the ##""^@ "C" -> ""^@ "F"## conversion.

This demonstrates that the Fahrenheit scale has different intervals in comparison to the Celsius and Kelvin scales.
