We do often wear large coats in winter and shorter clothes in summer noticing the temperature of the environment outside. But what does this temperature mean here? It is a physical quantity used to measure the degree of coldness or hotness. Point where Celsius and Fahrenheit Meets
Also, it can be defined as the indicator of thermal energy which is existing in every forms of matter. Using this measurement of heat energy, a person can determine and compare their own body concerning another one.
This temperature is measured commonly with the help of a device called a thermometer. Further, thermometers can be calibrated in different scales of temperature that have been used as standard and reference points.
Two main types of such scales include the Fahrenheit scale (symbolized as °F) and the Celsius scale (indicated as °C). Let’s learn more about these scales in this article.
The Celsius scale.
The Celsius scale ( formerly known as the centigrade scale) is a unit to determine the range of temperature of the substances Anders Celsius (1701–1744), a Swedish astronomer, developed a temperature scale. After this, the scale was named “the Celsius scale” in 1948 to give him the honor for his contribution. Before 1948, the scale was named centigrade which was taken from the Latin word “centum” which means the steps.
We already know that the freezing point of water is 0 °C with a boiling point being 100 °C. But do you know that these values were different earlier? During the 1740s the values for these temperature points were proposed to reverse by Jean Pierre Christin. The values included the freezing point of degree at 100°C whereas the boiling point was at 0 °C. Point where Celsius and Fahrenheit Meets
The Fahrenheit scale.
The Fahrenheit scale was originally developed by Daniel Gabriel Fahrenheit, a physicist and Dutch republic in 1724. He devised the mercury to be used in a glass thermometer and another thermometer called Fahrenheit scale. This scale is determined with the help of two fixed points with a separation of 180 °F. The separation includes:
- The boiling point of water i.e, 212 °F.
- The temperature at which the pure water freezes into ice i.e, 32°F.
Both of these points are taken at sea level with standard atmospheric pressure. Even though the use of this scale is limited nowadays, it is extensively used in the US mainly in the states of the Cayman Islands, the American colony of Liberia, and the western pacific.
The standard Fahrenheit temperature of the human body was initially set to 90 °F and then changed to 96 °F. Also, for ice water, the value was set to 32 °F. Further, due to the arrangement of boiling and freezing points, every degree of Fahrenheit is 1.8 times larger than one degree Celsius. Thereby, the Celsius degree is bigger than the Fahrenheit.
The Point where Celsius and Fahrenheit Meets.
Having different values for measuring the temperature with the varying unit, the two scales are linked through a value. More sepecifically, there is a point where the values for temperatures in degrees are equal for both the scales. This temperature is -40 °F and -40 °C.
Conversion of the two scales.
Both Celsius and Fahrenheit scale values can be converted to each other by using the algebraic formulas mentioned below:
For conversion of Celsius into Fahrenheit
°F = (°C * 9/5) + 32
For conversion of Fahrenheit into Celsius
°C = (°F – 32) * 5/9.
