Info about "Fahrenheit"
In the USA, the Fahrenheit scale with the unit degree Fahrenheit (°F) is still very common. Daniel Gabriel Fahrenheit was a German physicist who developed his temperature scale in 1714. Fahrenheit used, as the zero point of his scale, the lowest temperature he could produce with a mixture of ice, water and ammonia. This was -17.8 degrees Celsius, which he defined as the zero point of his scale, i.e., 0 degree Fahrenheit.
As a second and third fixed point, Fahrenheit defined the freezing point of normal water at 32 degrees Fahrenheit and the body temperature of a healthy person at 96 degrees Fahrenheit. In conjunction with the improved accuracy of measurements in the 19th century and the conversion method to todays Kelvin and Celsius degrees, the current fixed points of the Fahrenheit scale are at the freezing point (32 degrees Fahrenheit) and the boiling point of water (212 degrees Fahrenheit). With Celsius and Kelvin, there are 100 degrees, i.e., 100 scales, between the freezing point and the boiling point of water, whereas with Fahrenheit, there are 212 − 32 = 180 scales. Therefore, the conversion from Fahrenheit to, e.g., Celsius is done on the one hand via the shift of 32 degrees at the freezing point of water and on the other hand via the number of individual scale marks, i.e., the division into 180 instead of 100 degrees up to the boiling point of water. Thus, the Conversion formula for Celsius to Fahrenheit is as follows:
°F = °C × 1.8 + 32
The Fahrenheit scale is only officially used in the USA and its outlying areas, including Belize, the Bahamas and the Cayman Islands.
Info about "Celsius"
The common unit for temperature in German-speaking countries is measured in degree Celsius (°C). Anders Celsius, a Swedish astronomer, mathematician and physicist, defined this temperature division named after him, degree Celsius, in the 18th century.
He chose the melting point and boiling point of water as fixed points for the temperature scale and divided the change in volume of mercury between these points into 100 equal parts. So today we are used to water freezing at 0 degree Celsius and water boiling at 100 degrees Celsius. And to measure the temperature, mercury thermometers are often still in use.
Celsius thus forms a so-called empirical temperature scale, i.e., an arbitrary determination of the magnitude of the temperature by indicating the temperature in relation to a reference value. For degree Celsius, the arbitrary determination, as described, is between 0 degree and 100 degrees, depending on the aggregate state of the water.
While Kelvin is the base unit for temperature in the international system of units SI (Système international d'unités), degree Celsius (°C) is an officially derived SI unit. As a derived SI unit, the degree Celsius (°C) is officially approved in many European countries, especially in Germany, Austria and Switzerland.
