Useful site: temperature conversion

Question

I was struggling with the math for a conversion from Fahrenheit to Celsius and found this site that others may find useful. I didn't find it posted in a quick search of other answers.

here

So now I can say

Estamos a 35 grados.

and unfortunately that is true here today.

¡Qué lástima!

this is a very helpful question - JoyceM, Aug 13, 2010

Answer 1

°F=9/5(°C)+32°

212=9/5(100)+32

Remember this simple formula. You may not always have access to your computer or online access.

If you can remember that 100°C=212°F (boiling point of water at STP) you will always be able to figure out whether you multiply by 9/5 or 5/9 and whether you add or subtract the 32°.

100°C=(212-32)°F x 5/9

Fractions? Really Quenitin? You are giving me too much credit. :) - Nicole-B, Aug 13, 2010

Answer 2

This is excellent for me. I often try to tell friends in different parts of the world what the temperature is like where I live. I can never quite get it right.

I wish the U.S. would finally make the leap and join the metric system with the rest of civilization.

Which is why I got it, posting on Facebook to a friend in Germany. You know you're middle aged (or worse) when all you can think of to complain about is the weather. - revmaf, Aug 13, 2010

In my case, it is usually for friends visiting. I have had friends from the Ukraine, Philippines and the Dominican Republic who were traveling to visit us in the winter. I was always worried that I mislead them with the wrong conversion since they needed - Nicole-B, Aug 13, 2010

Answer 3

Another good one to memorize is 100 degrees Farenheit.

That's 37.7 degrees Centigrade.

When people in Europe start freaking out about the temperature being over 38 degrees, those of us who understand Farenheit will understand why.

I had this experience in Seville, Spain last summer. When we were there in August, it was the hotest place in Europe that day. It was over 40 degrees Celsius. That's 104 degrees Farenheit -- HOT, HOT, HOT

Answer 4

Do you know - I have a hard time remembering how hot 80 F is. I wonder how many countries in the world use Farenheit? (sp?)

i find that if you double it then add 30 ...you usually get the right conversion...for example....if its 30deg...double it =60deg add 30=90 deg....usuallly works every time.. - mariespain, Aug 13, 2010

Oh, thank you so much! That is quick and easy - so even say 15 (morning here) double is 30 add 30 - approx 60 F? Wow, that is great!!!! - margaretbl, Aug 13, 2010

Answer 5

Everyone knows 32Ff=0C and 212 F=100C. Beyond that, useful ones to know are 98.6F=36C (body temperature) and 70F=21C (room temperature). Anything more, is "icing on the cake".

I didn't know that :( - Kiwi-Girl, Aug 13, 2010

Actually those are useful numbers to know. And I didn't know them. ;) - revmaf, Aug 13, 2010

Answer 6

@ Margaret, this from Wikipedia

The Fahrenheit scale is used in the United States, Jamaica, Palau, Belize[2], Burma,[citation needed] and Liberia[10] for non-scientific applications. Most other countries have adopted Celsius as the primary scale in all use.

Nice, thankyou M-C - I had to google Palau, getting so slow in my old age, sigh...Very interesting to know this!! - margaretbl, Aug 13, 2010
