The Kelvin scale is a thermodynamic temperature scale where zero defines the point at which molecules give off no heat and all thermal motion ceases. In order to convert Kelvin measurements into Fahrenheit or Celsius, a simple plug-and-chug is all that's called for.

    The formula is: ºF = 1.8 x (K - 273) + 32. [1]

    The Kelvin temperature in this example is 373 K. Remember that you should not use degrees when measuring the temperature in Kelvin. [2]

    [3] Just subtract 273 from 373. 373 - 273 = 100.

    [4] Now, multiply the answer, 100, by 1.8. 100 * 1.8 = 180.

    Just add 32 to 180 to get your final answer. [5] 180 + 32 = 212. Therefore, 373 K = 212ºF.

    [7] Just subtract 273 from 273. 273 - 273 = 0. Therefore, 273K = 0 ºC.

    How do you convert fahrenheit to kelvin?
    Community Answer
    Convert from Fahrenheit to Celsius, then convert from Celsius to Kelvin.°F ->°C; [°C] = ([°F] - 32) × 5/9; °C ->K; K = [°C]+273.

      Tips

      • For very precise conversions use 273.15 instead of 273.
        Thanks
      • Scientists generally omit the word "degree" when using Kelvin. Say '373 Kelvin' instead of '373 degrees Kelvin'.
        Thanks
      • Any temperature difference will come out the same for Kelvin and Celsius. For instance the temperature difference between boiling water and melting ice can be calculated as follows:
        • 100 ºC - 0 ºC = 100 ºC or
        • 373.15 K - 273.15 K = 100 K
