FahrenheitToCelsius

// Created by Tan
// Program designed to convert Fahrenheit to Kelvin, and allow additional incremental conversions.
// Formula used:  Kelvin = (Fahrenheit - 32) * 5 / 9 + 273.15
// Derived from these equations, where the variables are their corresponding numbers degrees, Fahrenheit is °F, etc:
// (Fahrenheit - 32) * 5 / 9 = Celsius , Kelvin = Celsius - 273.15
