    Learn the formula. There are two ways that you can convert from Fahrenheit to Kelvin, and the first is a simple calculation that makes the conversion directly. The formula to use for this is K = (y °F + 459.67) x 5/9.[1] X Research source For example, if you needed to convert 75 °F to Kelvin, the formula would look like K = (75 °F + 459.67) x 5/9
    Add 459.67 to your original temperature. On the Fahrenheit scale, absolute zero is -459.67 °F, which is equivalent to 0 K.[2] X Research source Because the Kelvin scale does not contain negative numbers, you must first add 459.67 to any Fahrenheit number when you want to make the conversion to Kelvin. In the example of converting 75 °F, the answer to the first step is 75 °F + 459.67 = 534.67
    Multiply the sum by 5/9 to get the temperature in Kelvin. Remember that 5/9 can also be written as 0.55, where 5 is a repeating decimal. The answer to that product is your temperature in Kelvin.[3] X Research source In the example of 75 °F, the answer to the second step is 5/9 x 534.67 = 297.0388, where 8 is a repeating decimal The answer to (75 °F + 459.67) x 5/9 = 297.0388 Therefore 75 ...
    For easy conversions, remember that the boiling point of water is 212 °F = 100 °C = 373 K. The freezing point of water is 32 °F = 0 °C = 273 K. Thanks Helpful 6 Not Helpful 1

  3. The formula to convert from Fahrenheit to kelvin is: kelvin = (((Fahrenheit - 32) x 5) ÷ 9) + 273.15. Conversion Example. Next, let's look at an example showing the work and calculations that are involved in converting from Fahrenheit to kelvin (°F to K). Fahrenheit to kelvin Conversion Example. Task: Convert 70°F to kelvin (show work) Formula: .

  4. May 5, 2019 · How to Convert Fahrenheit to Kelvin. By Anne Marie Helmenstine, Ph.D. Which formula you use depends on how many significant figures you are working with in the conversion problem. It's more accurate to say the difference between Kelvin and Celsius is 273.15, but most of the time, just using 273 is good enough. T K = 37 + 273. T K = 310 K.

  5. Example 1: Convert 100 degrees Fahrenheit to Kelvin. Solution: To find: Temperature in Kelvin. T F = 1000 F(Given) Using Fahrenheit to Kelvin formula, (T) K = 5/9 [(T) F + 459.67] Putting the value: = 5/9(100+459.67) = 5/9(559.67) = 2798.35/9 = 310.93 K. Therefore, 100 degree Fahrenheit = 310.93 K.

  6. May 3, 2018 · There are a few different ways of writing the Fahrenheit to Kelvin conversion formula. It does not matter which one you use, so choose the one that is easiest. K = 5⁄9(°F – 32) + 273.15. K = 5⁄9(°F + 459.67) K = (°F – 32) /1.8 + 273.15. K = (°F + 459.67) /1.8.
