Converting Fahrenheit to Kelvin

This example problem illustrates the method to convert Fahrenheit to Kelvin.

Problem:

A healthy person has a body temperature of 98.6 °F. What is this temperature in Kelvin?

Solution:

First, convert Fahrenheit to Celsius. The formula to convert Fahrenheit to Celsius is

T_C = 5/9(T_F - 32)

T_C = 5/9(98.6 - 32)
T_C = 5/9(66.6)
T_C = 37 °C

Next, convert °C to K:

The formula to convert °C to K is:

T_K = T_C + 273

T_K = 37 + 273
T_K = 310 K Answer:

The temperature in Kelvin of a healthy person is 310 K.
