Example: 52.2 + 32 = 84.2 degrees Fahrenheit. To calculate the change in temperature, subtract the initial temperature from the final temperature. Example: 84.2 degree Fahrenheit - 41 degrees Fahrenheit = 43.2 degrees Fahrenheit The temperature from morning to afternoon changed by 43.2 degrees Fahrenheit.tep 4. Step 5. Obtain the two temperature readings for which you want to calculate the change. As an example, consider the readings from the introduction: 41 degrees Fahrenheit and 29 degrees Celsius. Before you can calculate the change in temperature, you must convert both measurements to the same unit.
