About Fahrenheit and Celsius
The Fahrenheit temperature scale is named for German physicist Daniel Gabriel Fahrenheit and is the measurement of temperature commonly used by the United States (and its associated territories) and by several nations in the Caribbean. On the Fahrenheit scale, water freezes at 32°F and boils at 212°F (at sea level).
The Celsius temperature scale—originally called centigrade and later renamed for Swedish astronomer Anders Celsius—is used almost everywhere else in the world. On the Celsius scale, water freezes at 0°C and boils at 100°C (at sea level).

Awesome work guys. Keep providing good content. Thank you
O Canada!
I spent four years in Montréal, where the weather forecast is always in Celsius; and I found that the easiest way to translate to the more familiar Fahrenheit was NOT to do the precise calculations in my head, or keep whipping out a device, but just to learn the 10s:
-20C = -4F
-10C = 14F
0C = 32F
10C = 50F
20C = 68F
30C = 86F
40C = 104F
That gets you in the right ballpark immediately, and I never found it important to distinguish between, say, 63 and 65 degrees F - especially because other factors, like wind speed and humidity, will make a much larger difference in how hot or cold you actually feel. That range - a mere seven numbers to commit to memory - is really all you need; anything below -20C is "too damn cold", and anything above 40C is "too damn hot".

EASIEST way to convert Celsius to Fahrenheit
The Quickest way I've found converting ℃ to ℉ without doing fractions or decimals is to round off to the nearest 10th (i.e.10℃,20℃,30℃.....) just remember 0℃ is 32℉ and there is 18℉ difference between every 10℃ and 9℉ between every 5℃. If you need a more accurate reading just add or subtract 1.8. Examples:
10℃=50℉ 15℃=59℉ 11℃=51.8℉ 12℃=53.6℉.....
20℃=68℉ 25℃=77℉ 21℃=69.8℉ 22℃=71.6℉.....
30℃=86℉ 35℃=95℉ 31℃=87.8℉ .......
40℃=104℉ 45℃=113℉ .....
50℃=122℉ 55℃=131℉......
60℃=140℉ 65℃=149℉.....
70℃=158℉ 75℃=167℉.....
80℃=176℉ 85℃=185℉.....
90℃=194℉ 95℃=203℉....
100℃=212℉ 105℃=221℉
temperature conversion
Here's a much simpler method for those not keen on algebraic equations. For a good approximate:
To convert centigrade to Fahrenheit: simply double the degrees in C, and add 30 .
for example 20deg C is app equal to 40 plus 30= 70 def F
To convert Fahrenheit to Centigrade: simply subtract (minus, or take away) 30 from degrees in F, and half it
for example: 70 deg F i.e 70-30 = 40, divide 40 by 2 ( or half that amount) = 20 deg C

There are three popular temperature scales used in math and science. You will often find yourself having to convert units between these scales. Using examples, we will learn how to perform these conversions, and also relate temperatures expressed in Kelvins, degrees Celsius and degrees Fahrenheit.
Easy Way to Convert from Celsius to Fahrenheit:
Instead of using F=(9/5)C+32; it is easier if you don't have a calculator to use (2)C+32-C/5.
Estimates are easy if you round to the nearest 5.
Example:
20C = 2(20)+32-20/5=40+32-4=68F
The benefit of using this formula is that it is easier to use in your head and the answer is exact; So it works in a calculator too!
Yo
So what is the formla for izt then

it is not "izt" it is usually "it" but the truth is I don't know...

Best site......keep on giving us shortcuts
My reference notes from what I learned here
Convert Celsius To Fahrenheit
20°c
1. Multiply # By 1.8
2. 20x1.8=36
3. Add (32)
4. 36+32=68
Convert Fahrenheit To Celsius
68°f
1. Subtract (32) From #
2. 68-32=36
3. Multiply by .5556 (or 5/9)
4. 36x.5556=20
4.1. Or 56 Instead Of .5556
4.2. 36x56=2016
4.3. Remove 16
Using Method 5 Divided By 9
1. Multiply By 5
2. 36x5=180
3. Divide By 9
4. Turn 9 To 10
5. 180/10
6. Half 180 To 90 And 10 To 5
7. Half 90 To 40 And 5 To 2
8. Half 40 to 20 And 2 To 1
9. 20/1=20
7. 40 is easier to half then 45
Keep going until you can't half 10 anymore or don't half 2
My notes to help remember this. Used to be good at math suck at it now
please I need more examples
please I need more examples on how to convert from f to c
Compliment!
This was very helpful! Thanks so much!
82•F - 32 = 50 (now) 50*.556
82•F - 32 = 50 (now)
50*.556 = 27.8•C (exact)
Unless you need the EXACT
Unless you need the EXACT number, you can do a quick conversion in your head:
70F - 32 = 38 divided by 2 = 19, then add 1 or 2(remember, this is close enough, not exact)= 21C. The exact conversion would be 21.1.
Another example is 40F - 32 = 8 divided by 2 = 4C. For a lower F temperature to start with, you don't have to add much. In this case, the exact conversion is 4.4.
why is it so many formula
why is it so many formula method to convert in the different version?
F into C Subtract 32,
F into C
Subtract 32, multiplyng by 5, and Divided by 9
Ex-
50 F = C
50-32=18
18*5=90
90/9=10 C

Yo ppl! Conversion of C to
Yo ppl!
Conversion of C to F.
Take the value of C, multiply it by 2.
then subtract the first digit of the answer from the answer, then simply add 32.
Example: 10C to F ?
10*2=20
20-2=18
18+32=50F
Go vice versa too.
Have fun!
This will not work is above
This will not work is above 99C or below -99 C
C to F
C+40 *9/5-40=F
F+40*5/9-40=C
will work at any temp
Formula is not always correct
If you use this formula for simply 100C (Boiling which should equal in the end 212F) it works out 100Cx2=200, 200-2=198, 198+32=230F, so it works out incorrectly in this situation. the formula is not always correct so it should not be used as a solid formula. It also is incorrect in other examples that I worked. Wish it worked because it's simple but not.
