Knowing how to convert between Fahrenheit and Celsius measurements is important. Why? There are many factors I can think of such as.... What if you don't have one handy around? What if the internet is down and no online calculator is available? What if you encounter a problem like this on the CBET exam? (Hint! Hint!) My point is the greatest calculator or microprocessor ever invented is the one sitting between your ears. We must not forget that that are manual ways to do things although it takes longer we should not forget who we are. BiomedGuy 22:00, December 18, 2010 (UTC)
