Whats the relationship between fahrenheit and Celsius?

Question

PLEASE HELP

Answer 1

Tf=(9/5)*Tc+32

Answer 2

Before we discuss the difference between the two temperature scales, let's focus on the similarities. Both scales are based on the freezing conditions of water, a very common and available liquid. Since water freezes and boils at temperatures that are rather easy to generate (even before modern refrigeration), it is the most likely substance on which to base a temperature scale.

On the Fahrenheit scale, the freezing point of water is 32 degrees and the boiling point is 212 degrees. Zero Fahrenheit was the coldest temperature that the German-born scientist Gabriel Daniel Fahrenheit could create with a mixture of ice and ordinary salt. He invented the mercury thermometer and introduced it and his scale in 1714 in Holland, where he lived most of his life.

Anders Celsius, a Swedish astronomer, introduced his scale is 1742. For it, he used the freezing point of water as zero and the boiling point as 100. For a long time, the Celsius scale was called "centigrade." The Greek prefix "centi" means one-hundredth and each degree Celsius is one-hundredth of the way between the temperatures of freezing and boiling for water. The Celsius temperature scale is part of the "metric system" of measurement (SI) and is used throughout the world, though not yet embraced by the American public.
To convert Fahrenheit temperatures into Celsius:

* Begin by subtracting 32 from the Fahrenheit number.
* Divide the answer by 9.
* Then multiply that answer by 5.

Here's an example: Change 95 degrees Fahrenheit to Celsius: 95 minus 32 is 63. Then, 63 divided by 9 is 7. Finally, 7 times 5 is 35 degrees Celsius. Time to go to the beach!

To convert Celsius temperatures into Fahrenheit:

* Begin by multiplying the Celsius temperature by 9.
* Divide the answer by 5.
* Now add 32.

Here's an example: Change 20 degrees Celsius to Fahrenheit: 20 times 9 is 180. Then 180 divided by 5 is 36. Finally, 36 plus 32 is 68 degrees Fahrenheit. That would be a pretty comfortable outside temperature for taking a walk!!

Using an Algebraic Formula:

For the mathematically daring, here is the algebraic formula used for conversion from Fahrenheit to Celsius:

Tc=(5/9)*(Tf-32)
Tc=temperature in degrees CelsiusTf=temperature in degrees Fahrenheit
* means multiply

Now, to convert from Celsius to Fahrenheit,:

Tf=(9/5)*Tc+32
Tc=temperature in degrees CelsiusTf=temperature in degrees Fahrenheit

Answer 3

Fahrenheit and Celsius are two different temperature measurement standards. Essentially, they only differ in the size of their units and the absolute temperatuere at which they are "zeroed".

The Fahrenheit scale was developed in the early 1700's and there are are competing stories as to exactly how and why the size of the scale and it's zero point are exactly such, but the most important thing to know about it is that it is essentially arbitrary. That is, the scale was decided upon and THEN physical measurements were made based upon it. The Fahrenheit scale was the standard for many many years and remains useful for two reasons. One is that Americans "think in Fahrenheit". When an American is told that it is 65 Fahrenheit degrees outside, they know what that feels like. If an American is told that it is 45 Celsius degrees outside, they don't know if that will feel cold or hot. (In fact, that would be very hot!!) Fahrenheit is also useful because the 0 to 100 portion of the scale is right where the outside weather temperature typically sits. It does get colder then zero and it does get warmer than 100, but in general, most of the time the outside temperature is somewhere on that convenient scale.

The Celsius scale was developed in the mid 1700's but was not formally adopted as the standard international temperature until 1948. The Celsius scale was initially designed by taking the freezing point of water (melting point of ice) as the zero point and the boiling point of water as 100 degrees. The scale was thus divided and the size of an individual degree, determined. At present, the formal definitions involve the concepts of absolute zero and the "triple point" of water, but the practical outcome is the same, i.e., zero is where (under appropriate standardized conditions) water freezes/ice melts and 100 is where water boils.

Since these two scales are just different units measuring the same thing, they can be easily converted back and forth. We can derrive the relationship between the two right here by acknowledging a couple of baseline facts:

In Fahrenheit scale, water freezes at 32 degrees and boils at 212 degrees. In between are 180 degrees.

In Celsius scale, water freezes at 0 degrees and boils at 100 degrees. In between are 100 degrees.

Therefore, the following is true:

180 F degrees / 100 C degrees = 1, or more simply:

The size of an F degree is 5/9ths of a C degree, or a C degree is 9/5ths of an F degree.

To convert, then, one simply figures out how many degrees above (or below) the freezing point of water the temperature measurement is, and then uses the above proportionality.

For example: 45 C degrees.

45 C is 45 degrees above water freezing.
45 * 9/5 = 81 F degrees above water freezing.
Since water freezes at 32 F, add 32
45 C = 113 F

82 F:

82 F is 50 F degrees above water freezing. (Subtracting 32)
50 * 5/9 = 27.8 C degrees above water freezing (approximately).
Since water freezes at 0 C, 27.8 is our answer.

82F = 28 C

In general:

(temp F - 32) * 5/9 = temp C
(temp C * 9/5) + 32 = temp F


I hope that answered your question!

Answer 4

c/5=(f-32)/9

C-Celsius scale
F- Fahrenheit Scale

To Convert Fahrenheit to Celsius:

If F is the Fahrenheit degree:

C= 5*(F-32)/9

To Convert Celsius to Fahrenheit:

If C is the Celsius degree:
F=9*C/5 + 32

Answer 5

C/100=(F-32)/180
Where
C ->Temperature in Celcius
F-> Temperature in Fareheit
