Fahrenheit is a temperature scale originally used to measure a temperature range of real-life things. The zero point was the temperature of an equal mix of salt and ice water and 100 degrees above that was the temperature of a human being. Over the years, this temperature scale was defined by the melting point of water ice (32 ­­°F) and the boiling point of water (212 °F) and the size of the individual units have not changed much. We can relate Fahrenheit to Kelvin by converting Fahrenheit to Celsius using the formula:

°C = 5⁄9(°F – 32)

where °F and °C are the temperatures in Fahrenheit and Celsius respectively.

Since these two equations equal the same thing (°C), they equal each other.

K – 273.15 = 5⁄9(°F – 32)

Now you have the formula to convert between Kelvin and Fahrenheit. We want to know when K = °F, so plug in K for °F in the formula.

K – 273.15 = 5⁄9(K – 32)

Solve for K. First, get rid of the parenthesis

K – 273.15 = 5⁄9 K – 17.78

Subtract 5⁄9 K from both sides

K – 5⁄9 K – 273.15 = 17.78

Add 273.15 to both sides

K – 5⁄9 K = 17.78 + 273.15

K – 5⁄9 K = 255.37

9⁄9 K – 5⁄9 K = 255.37

4⁄9 K = 255.37

Multiply both sides by 9⁄4

K = (255.37)9⁄4

K = 574.59

At 574.59 Kelvin, the Fahrenheit temperature will be 574.59 °F.
