When people respond to posts, I see the term OP used. Does that mean Original Poster, or Other Person? Just curious. It didn't take me long to figure out BG meant bad guy, and I had to ask my husband what EDC meant (everyday carry) but having trouble with OP.
Sorry to be so dense.
i wonder how many people just counted the alphabet on their fingers....
I will have a bit of time after my knee operation so I will try to learn that skill whenever I will be awake and sober, F-Chen...nice to have something to do when I am bored. LOLi wonder how many people just counted the alphabet on their fingers....

Practice changing degrees Celsius into degrees Fahrenheit in your mind. Then when you are up and about again and see a temperature given in Celsius on one of those roadside Time/Temperature signs you can do the math in your head in about ten or fifteen seconds and say to yourself, ah, the real temperature is xx degrees.
It is as simple as ADD (or double), SUBTRACT (10%), ADD (32) = Answer.
Or: ADD, ADD, SUBTRACT = Answer.
20C= 20 + 20 = 40 - 4(10%, remember) = 36 + 32 = 68F
21C= 21 + 21 = 42 - 4.2 = 37.8 + 32 = 69.8F
25C= 25 +25 = 50 - 5 = 45 + 32 = 77F
0C= 0 + 0 = 0 - 0 + 32 = 32F
100C= 100 + 100 = 200 - 20 = 180 + 32 = 212F
You may be able to do the subtracting second instead of first, that would look like 100C= 100+100=200+32=232-20=212F. It all depends on how you work with numbers in your mind and move them around. For the example using 33C, I add 33 and 33 and 32 getting 98 and then I subtract 7 (easier than subtracting 6.6 in my mind) getting 91 and THEN adding the .4 back onto the answer, getting the 91.4F.
20C= 20+20+32-4=68F
40C= 40+40+32-8=104F
33C= 33+33+32-6.6=91.4F
And, you can do it the other way too, but not quite as easy... in your mind of course, no pen and paper while driving down the street. LOL
I just can't seem to do the way the books show of taking the C x 9 / 5 + 32 = F.
Now you will have something else to keep you busy.
And once you learn how to do that easily, someone will say something like "It was 45C today" and you do the 90 122 - 9 and say "oh, it got up to 113 degrees out huh?" as fast as you just read that and they will look at you kind of strange, like you are really smart. USUALLY what you hear said will be "How did you do that so fast?"
Enjoy,

IS there going to be a test on this?
Thanks for the suggestion, Ken...Learning cooking from scratch, I think I am pretty good at temperature. I also came from Australia where we use C° instead of F°. And my stove over there in Oz is in gas as opposed to my stove here which is electric. One day I will be able master all of these brain exercises...LOLPractice changing degrees Celsius into degrees Fahrenheit in your mind.

You reminded of a game we used to play with beer -- sucking it with a straw! Man! That was awful!!! LOLYOU are the one who will have to decide on the answer to that. Some people are happy with the "Hum, 45C, wonder how hot that is?" and drive on down the road. It only takes a couple minutes to learn how to do it in their head for those who are able to do it. Others can't learn how to do it, their mind isn't setup that way, they aren't able to move numbers around in their mind. For those that can, they enjoy doing small quick things like that.
It is like...ummm, most people like sucking on a straw when they have a milkshake. I can't do that, it gives me a headache, so I drink it instead. Everybody is different, a lot of them just a little bit different, and some a LOT different.
AND, I have always enjoyed learning something new, everyday.

I have never been able to remember the equation for this. I think you've just cured me-thanks.
Like everything else in life there will be a test-usually when you least expect it.
