Essay: History of the Fahrenheit and Celsius scales

The history of the Fahrenheit and Celsius scales dates all the way to the early 1700’s.  The Fahrenheit scale was created by a German physicist by the name of Daniel Gabriel Fahrenheit. (abyss.uoregon, n.d.)  The year that it was created was in 1724. (What Is The History of The Fahrenheit Scale, n.d.)
The reason the Fahrenheit scale was created was because Daniel didn’t like fractions of the other temperature systems. (Rozell, 1996) Also, he wanted to make the scale more convent for people. (Rozell, 1996)
The Fahrenheit scale was created by a man by the name of Carlo Rinaldi, had made up a scale that represented the freezing points and boiling points of water.  Another man by the name of Roemer came to the conclusion that the temperatures should be taken into consideration.  Those temperatures were the human bodies temperature and the lowest temperature that you got when you mixed ice and water together.  After that, Roemer now had four points.  Zero which was the lowest temperature and sixty which represented boiling water.  He chose the number sixty because it represented the number of minutes in an hour and the number of seconds in a minute.  So, in the scale he created, Roemer concluded that 7.5 degrees was for ice freezing and that 22.5 degrees was body temperature.  Then, now is how Daniel Fahrenheit came into the equation.  Daniel took the numbers that Roemer came up with and multiplied then by four.  This now made the scale have a total of four points which was 0 degrees representing the low temperature, thirty degrees representing the temperature of ice, 90 which represented body temperature, and last 240 degrees that represented boiling water.  After he did all of that, he noticed that the numbers didn’t quite match up correctly.  He noticed that the temperature for the human body was too low so he had changed it from ninety degrees to 96 degrees, which is still not the actual normal human body temperature as we know it today to be 98.6 degrees.  Since he had to change the temperature for the human body, he had changed the freezing point to 32 degrees.  So that means since he changed the human body temperature and the freezing point temperature, he had to change the boiling point temperature.  The reason he had changed it along with the others was because Roemer had used alcohol in the thermometers.  The reason that was so important was because alcohol boils at a different temperature then water does.  So Daniel had once again adjusted his scale.  He had made the boiling point from 240 degrees to 212 degrees so that it would go along with his other measurements he had taken. (That Wierd Fahrenheit Temperature Scale, 2005)
As outlined in the previous statement above, you could see all of the changes that the Fahrenheit scale had undergone before it had come to the final scale that we know today.
The Fahrenheit scale has always been used for telling temperatures of some sort.  It was used up until the 1960’s for industrial, climatic, and medical reasons in the English speaking regions.  In the mid too late 1900’s, the government had tried to make us convert too Celsius, but it didn’t work out.  Now, we use the Fahrenheit scale to tell the temperatures of the air around us, which usually ranges anywhere from zero degrees Fahrenheit to 100 degrees Fahrenheit. (Fahrenheit, 2016)
To prove the conversion form from Fahrenheit to Celsius, first the equation needs coordinates that will come from the freezing point and boiling point from Fahrenheit and Celsius.  The freezing point of water for Celsius is zero degrees and   the freezing point for water in Fahrenheit is 32 degrees, so the first set of coordinates will be (0,32).  The second set of coordinates will be the boiling point temperatures.  The boiling temperature of water in Celsius is 100 degrees and the boiling temperature of water in Fahrenheit is 212, so that will make the second set of coordinate (100,212).  The results below will give the equation for the conversion from Fahrenheit too Celsius.

Next on the list, is the Celsius scale.  The Celsius scale was created by Anders Celsius. (History of the Celsius temperature scale, n.d.)  The scale was invented in 1742. (abyss.uoregon, n.d.)
The Celsius scale was created because Anders Celsius said that it helped him with his science.  Also he created it because he wanted to receive more accurate results of temperature measurements.  The reason he liked to use mercury along with natural air was because it gave two readings, which would confirm the accuracy of the temperature. (Celsius, 2013)
Mr. Anders Celsius created the Celsius scale by creating a backwards version of what we know today to be known as the modern day Celsius temperature scale, where
zero was being used to represent the boiling point of water and 100 to represent the freezing point of ice. (Celsius, 2013)
There hasn’t been very many changes that happened to the Celsius scale.  The only change that the Celsius scale had underwent was that Anders had flipped the freezing and boiling point temperatures around.  Previously calculated as 100 degrees Celsius, the freezing point of water on the Celsius scale is now zero degrees, contradicting to the boiling point, which changed from zero to 100 degrees.  They were just flip flopped. (Celsius, 2013)
Worldly scientist still use the Celsius scale. Other than scientist, people use it where the metric scale is dominant rather than standard use. (abyss.uoregon, n.d.)
To prove the conversion form from Celsius too Fahrenheit, you used the points that we had previously worked out.  The results in proving the conversion formulas will be followed.
