This is Giancoli Answers with Mr. Dychko. Temperature in kelvin is 273.15 more than the temperature in Celsius. And so we can find the temperature in Celsius is can be temperature in kelvin minus 273.15. And then we have this formula for the temperature of Fahrenheit in terms of Celsius, it's 9/5 times the temperature in Celsius plus 32. And then we can plug in what we just figured out for converting from kelvin to Celsius and for the Celsius temperature here. So, we have temperature in kelvin minus 273.15 is a Celsius temperature written in kelvin. And then we can plug in and get our conversion to Fahrenheit. So, we have 0 degrees kelvin is absolute 0 minus 273.15 times 9/5 plus 32 gives negative 459.67 degrees Fahrenheit is what an absolute 0 is in Fahrenheit.
