Can someone please try to explain Celsius to me?

Question

I really don't understand it, I use fahrenheit...

Answer 1

It's a temperature scale that takes the melting and boiling points of water (at standard atmospheric pressure) as its basis. Ice melts at 0°C and water boils at 100°C. Interestingly, its inventor, Anders Celsius, had the scale reversed - melting at 100° and boiling at 0°, but it was flipped after Celsius' death a couple of years later by Carl Linnaeus (he of the Linnaean taxonomy system) for some thermometers he had made for greenhouses.

Answer 2

The Celsius scale has 100 divisions between the freezing point and the boiling point of water. Water freezes at 0 C and boils at 100 C. On the Fahrenheit scale, water freezes at 32 F and boils at 212 F. So, there are 180 divisions between freezing and boiling on the Fahrenheit scale.

There are 1.8 divisions on the Fahrenheit scale for every 1 division on the Celsius scale (180/100 = 1.8), so a Fahrenheit degree is smaller than a Celsius degree.

To convert from F to C:

C = (F - 32) / 1.8

You subtract 32 from the Fahrenheit reading first because the F scale has a 32 degree "head start". Then, you divide by 1.8 because it takes 1.8 F degrees to equal a C degree.

To convert from C to F:

F = 1.8 C + 32

You multiply the C reading by 1.8 first because there are 1.8 times more F degrees between the m.p. and b.p. of water. Then, you add on 32 because the F scale has a m.p. for water of 32.

Answer 3

The Celsius temperature scale was previously known as the centigrade scale. The degree Celsius (symbol: °C) can refer to a specific temperature on the Celsius scale as well as serve as a unit increment to indicate a temperature interval (a difference between two temperatures or an uncertainty). “Celsius” is named after the Swedish astronomer Anders Celsius (1701 – 1744), who developed a similar temperature scale two years before his death.

From 1744 until 1954, 0 °C on the Celsius scale was defined as the freezing point of water and 100 °C was defined as the boiling point of water under a pressure of one standard atmosphere; this close equivalency is taught in schools today. However, the unit “degree Celsius” and the Celsius scale are currently, by international agreement[1], defined by two different points: absolute zero, and the triple point of VSMOW (specially prepared water). This definition also precisely relates the Celsius scale to the Kelvin scale, which is the SI base unit of temperature (symbol: K). Absolute zero—the temperature at which no energy remains in a substance—is defined as being precisely 0 K and −273.15 °C. The triple point of water is defined as being precisely 273.16 K and 0.01 °C.

This definition fixes the magnitude of both the degree Celsius and the unit kelvin as being precisely 1 part in 273.16 parts the difference between absolute zero and the triple point of water. Thus, it sets the magnitude of one degree Celsius and the kelvin to be exactly equivalent. Additionally, it establishes the difference between the two scales’ null points as being precisely 273.15 degrees Celsius (−273.15 °C = 0 K and 0.01 °C = 273.16 K)[2].

I am really happy that youasked that Question your clever very smart indeed some people say Well its Celsiuse ! hehe

Take care

Smart person you
