The Swedish astronomer Anders Celsius was born on December 14, 1701, in Uppsala. In his scientific life, he proposed a scale of temperature called the Celsius Scale.
- The Celsius Scale was created by Anders Celsius, born December 14, 1701, in Uppsala, Sweden. He was a student at Uppsala University that finished his doctorate there in 1730. In 1742 he became the assistant of the Astronomer Royal in Stockholm and later that decade became Director of the Astronomical Observatory at Uppsala University. In 1822 he died from an illness, but not before seeing other scientists adopt his thermometer as a way to measure temperature. He retired in 1754 and focused more on science.
- The Celsius Scale is based on a scale from 0 to 100. If someone were to be at the very end of the thermometer, they would feel that they are at a temperature of -100 degrees Fahrenheit but are actually at 0 degrees Celsius. The freezing point of water is 32 degrees Celsius, but it is negative 40 degrees Fahrenheit when converted to Fahrenheit. It gets these numbers by taking its zero points and adding 273.15 to it. The zero points for the Celsius Scale system are where all the mercury in the thermometer sits when it’s held in your hands or put in someplace where it will not move at all overnight. This is the base point for the thermometer. The melting point of ice is 0 degrees Celsius, but it is negative 32 degrees Fahrenheit when converted to Fahrenheit. When melted, all that mercury leaves the thermometer, and the scale leaves mercury.
- The Kelvin Scale was created in 1847 by William Thomson, brother of Lord Kelvin of Scotland, who created the absolute zero temperature scale. He was born on June 9, 1824, in Belfast, Ireland, and died on July 6, 1907. The Kelvin Scale uses absolute zero points, which are -273 degrees Celsius and -459 degrees Celsius. This means that if an object or item were to be at negative 273 or negative 460, it would be at absolute zero temperatures (except water). Kelvin also created the Kelvin Scale, which is used to measure heat and cold; however, it is more commonly known as the thermodynamic temperature scale.
- The British Parliament had a committee responsible for fixing temperatures, and they were based on scientific facts and time. However, they never could agree on what the absolute zero points should be. They used different scales to show how cold it would be but never agreed on a single point of coldness. This caused years of arguments and arguments by individuals who disagreed with their values. Eventually, Lord Kelvin became the supervisor for an international body that created a Rankine Scale scale in 1848 for this very reason. This scale was based on absolute zero and the Kelvin Scale.
- In 1856, Lord Kelvin was creating a scale based on absolute zero, and he noticed that mercury was at 32 degrees Fahrenheit. This is why the Kelvin Scale uses two points to show temperatures from 0 to 100 degrees. Likewise, in today’s thermometer, a point is used for measuring temperature, while a point is used to mark when an item or object reaches or surpasses a certain temperature. Today we use a degree because it’s easier to understand numbers in numbers than linear measurements, which are not as easy to comprehend.
- The Celsius scale uses a thermometer and a standard weight. This allows the scientist to make sure that their scale and their readings and values match up correctly at all times. When using the Celsius Scale, we mark the beginning point on the thermometer while it is sitting in our hands or somewhere where it won’t move while we sleep. We then notice how much mercury is left in the thermometer to get our reading for that day. We may take a reading once every hour to see if any changes have been made from outdoor environmental effects or from being near an object with extreme temperatures such as something burning or being near hot steam.
