Awesome work guys. Keep providing good content. Thank you
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".
thank you

Fahrenheit celius
50 - 32 divided 1.8 = 10
Y=a+bx (regression equation)
Y= Fahrenheit
x= Celsius
a=32

This was really helpful for school work!

Do the following conversions. Round to nearest tenth where necessary.
1. 55 oF = oC
2. 67 oF = oC
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℉
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
