In college Chemistry, I had discovered that when you were given temperatures in Fahrenheit, you did not need to convert to Kelvin and then take the natural log. A far easier method was to add 459.67 to the Fahrenheit values converting them to degrees Rankine, then just take the natural log. So much easier.
