What are degrees Celsius (° C)?
Celsius is calleda temperature measurement unit erroneously known as degrees Celsius and represented by the symbol ° C. This unit pays tribute to its creator, the Swedish physicist and astronomer Anders Celsius, and is equivalent in caloric intensity to the calibration of the Kelvin degrees, and then it can be defined with the post-obit formula:
Temperature (° C) = Temperature (M) – 273.15
Paradoxically, William Thompson, creator of the Kelvin calibration, created information technology based on the Celsius degree calibration, since it is later on. All the same, the latter is the i accepted by the International System, together with that of Celsius equally an accompaniment unit.
On the other hand, the conversion of degrees Celsius to degrees Fahrenheit is done by the following formula:
Temperature (° F) = 1.8 x Temperature (° C) + 32
The Celsius degree scale places its zero point (0) at near 0.01 degrees below the triple point of water: that in which the 3 states of matter, solid , liquid and gas , coexist in equilibrium .
Initially,its creator had been based on the freezing and humid points of water , assigning them 100 and 0 degrees respectively, and then that at a higher heat a lower temperature was recorded. This logic would exist reversed around 1744 when Jean-Pierre Christin and Carlos Linneo proposed to reverse information technology.

Anders Celsius
The creator of the Celsius scale was Anders Celsius (1701-1744), a scientist of Swedish origin. Built-in in the Swedish Empire, hewas a professor of astronomy at the University of Uppsala , where he supervised the structure of his observatory, in charge of which he was since 1740.
He was interested in observing the northern lights , in measuring the flattening of the planet at its poles, although his best known scientific contribution is the creation of the temperature scale that bears his name, which he proposed to the Swedish University of Sciences equally a replacement for the Farenheit calibration, of German origin.
He died in 1744, a victim of tuberculosis. Yet, in life heenjoyed numerous recognitions in the scientific surface area , as was his acceptance in the Imperial Society, in the Leopoldina University of Natural Sciences or the Prussian Academy of Sciences. Subsequently, one of the craters of the Moon was named in his honor.

Kelvin Degrees
Created by William Thompson Kelvin (called Lord Kelvin) in 1848, information technology was established using the Celsius scale, but relocating its zero point (0) to friction match the so-called absolute cipher (-273.15 ° C, minimum possible temperature) but retaining the same dimensions of the calibration. This thermometric unit is represented past the letter K and is considered the "accented temperature", whichis why itis used in the scientific field, peculiarly in physics and chemistry .
Kelvin grades are also used to measure the colour temperature in pic , video and photography . That is, a scale to measure out the colour compared to that emitted past a black body heated to a sure temperature in degrees Kelvin.

Farenheit degrees
Represented with the symbol ° F, the Farenheit degreewas proposed by the High german physicist and engineer Daniel Gabriel Farenheit in 1724 . According to its scale, the freezing and boiling points of water are 32 ° F and 212 ° F respectively, that is, unlike the Celsius scale, it does non use these points as defining limits.
Instead, Farenheit determined its goose egg betoken on the scale through a usual refrigeration mixture: ice, water and ammonium chloride. This is because he wanted to abolish the negative scales of the Rømer scale used until so.
