Do you know how to convert C to F Degrees?

[Bretrick]

And vicey versa?
C to F is, example, 30 C x 1.8 + 32 = 86 F
F to C is, example, 65 F - 32 x 5/9(.5555) = 18.3 C

I just look online. Its easiest.

Google it!

Either use Google, memorize the formula, look up the formula, or derive the formula (see below).
32F = 0C
212F = 100C
Linear relationship. so find the equation through points (0, 32) and (100, 212). Slope is (212-32)/(100-0) = 180/100 = 9/5. The y-intercept is (0,32).
Equation is y = mx + b or in this case F = (9/5)C + 32. Solve for C to get the other version (9/5)C = F - 32, C = 5/9 F - (5/9)*32, C = (5C)/9 - 160/9 or the more popular C = (5/9)(F - 32).

Very simple way to do it , and the way I always do it.. it gives a close enough estimate if not exact.., is to just double it and add 30... ie...15 deg c x2 =30.. plus 30 is 60 deg f

or 25 deg c.. double it is 50, add 30, makes 80 f

That is what I learnt many years ago as well. I'm talking 50 years ago.

Or more. I learned the equation when I was in high school but never had to use it after that, not even at university when I studied chemistry.

Celsius is definitely the way to go. In the digital age I cannot understand the reluctance to embrace decimal systems.

yes me too... I still think in Fahrenheit whereas my dd always in Celsius.. so when I say that it's going to be 70 deg f today she'll always ask ''what's that in Celcius''?.. because at 48 the only thing she ever learned was decimal.. ...so I just work backwards.. simple mental arithmetic.. knock off 30 and 1/2 the remaining... = 20 deg c

 

[Remy]

Not without Google.

 

[Knight]

Conversion isn't a daily problem for me. I don't even need Google Temp here is always in Fahrenheit so my go to is

Alexa what's the temp?

 

[Jules]

It’s lengths that bother me. Amazon knows I’m in Canada so lengths are metric. Pita.

 

[OneEyedDiva]

Well thank you Bretrick. Now I know...but easier is the conversion app on my computer. I'm sure I could find a similar app on my phone. This is the main page which has the drop down menu that includes temperature and other measurements.

[Rakaia]

My generation is fairly comfortable with both metric and imperial measurements.
A rough enough guide for C to F is add 15 and double it.
On my first motorcycle I thought 100 MPH was really fast...

 

[mrstime]

I use Fahrenheit exclusive, our son can use either. I dislike Celcius.

 

[Manatee]

I just reach into the drawer and get the converter that I bought in Radio Shack all those years ago.

 

[MarkinPhx]

We were taught those formulas when I was in grade school. At there time I think there was a big push for the US to go to the metric system and to convert to Celsius. I never really needed to use it until I first starting getting online in the early 90's and started to communicate with people from other countries.

Hollydolly: That's what we were told, it makes it so much easier.
