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.
To calculate Kelvin figure, simply add 273.15 number to the Celsius temperature degree and you get the temperature reading in Kelvin thermodynamic temperature unit: K = Â°C + 273.15 and correspondingly. Take the figure and you can manually convert it to Fahrenheit with: K = Â°F + 459.67 Ã 5/9.
