I will define only the Fahrenheit scale at this point. The Fahrenheit scale was made by a German physicist in 1724. The Celsius scale was not made until later, 1742 to be exact, by a Swedish astronomer. So in all reality "Fahrenheit" isn't really American as it was made in a completely different, unrelated part of the world, and it is an older means of temperature measurement as well. While we are one of the last ones to use such now, at one point in time, it was the only one to use. So what you will, its more "traditional".
