Example 3
Problem:
Express normal body temperature, 98.6°F, in °C and K.
Now, it’s your turn.
Solution
The Fahrenheit to Celsius conversion equation may be expressed in this form:
To solve for Celsius:
°C = (98.6 °F – 32) x 5/9 °C = (66.6) x 5/9 °C = 37.0
To solve for Kelvin:K = °C +273K = 37.0 + 273K = 310
Answer
98.6 °F is equal to 37.0°C and 310 K
