This example problem illustrates the method to convert Fahrenheit to Kelvin.
A healthy person has a body temperature of 98.6 °F. What is this temperature in Kelvin?
First, convert Fahrenheit to Celsius. The formula to convert Fahrenheit to Celsius is
TC = 5/9(TF - 32)
TC = 5/9(98.6 - 32)
TC = 5/9(66.6)
TC = 37 °C
Next, convert °C to K:
The formula to convert °C to K is:
TK = TC + 273
TK = 37 + 273
TK = 310 K
The temperature in Kelvin of a healthy person is 310 K.
