**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.
