Well, on the Celsius scale it is just additively different:

#"0 K" harr ul(-273.15^@ "C")#

The Fahrenheit scale has different increments to confuse us...

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

And thus, the temperature in #""^@ "F"# would be...

#-273.15^@ "C" xx 9/5 + 32 = ul(-459.67^@ "F")#

Answer:

Absolute zero is #"0 Kelvins"#. On the Celsius scale it is #-273.15^@"C"#, and on the Fahrenheit scale it is #-459.67^@"F"#.

Explanation:

There is no formula for converting Kelvins to degrees Fahrenheit, so you need to convert from Kelvins to degrees Celsius, and then degrees Celsius to degrees Fahrenheit.

Absolute Zero in Kelvins to Celsius

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

#"0 K"-273.15##=##-273.15^@"C"#

Absolute Zero in Celsius to Fahrenheit

#""^@"F"##=##""^@"C"xx9/5+32#

#""^@"F"##=##-273.15^@"C"xx9/5+32"##=##-459.67^@"F"#

You can substitute #1.8# for the fraction #9/5#.
