Tips for Easy Conversion of Celsius to Fahrenheit

Easy Conversion of Celsius to Fahrenheit

When traveling to Europe, you will notice that all the temperatures are stated in Celsius.  Since Americans are accustomed to the Fahrenheit system,  Celsius is quite a mystery to most of us.

But, I have found an easy way to convert Celsius to Fahrenheit that is not scientifically accurate, but good enough to give me a good idea as to what the temperature will feel like.

Whatever the Celsius is, double it and add 32. That will give you an approximate Fahrenheit temperature. For instance, if Celsius is 15 degrees, you will double it (30) and add 32, giving you an approximate Fahrenheit degree of 62.  No calculators needed!

Of course, if you want to be completely accurate, the formula is: F = (1.8 x C) + 32. So, if we use the previous example of 15 degrees Celsius, the actual degrees in Fahrenheit will be 59.

Another easy way to remember some key temperatures without any mathematical conversion of Celsius to Fahrenheit is to orient yourself on a few easy to remember temperatures:

Easy Conversion of Celsius to Fahrenheit0 C = 32 F

16 C = 61 F

28 C = 82 F

37 C = 100 F

100 C = 212 F

Our “cheater calculation” was certainly close enough for me; try it and it will make your calculations a snap!

I reference "relative" temperatures while trying to learn actual Celsius temps:

Of course we know 0C is 32F.

Then I remember these: 4C is 40F 10C is 50F 16C is 61F 20C is 68F (room temperature) 23C is 73F ("23 is 73") 28C is 82F.

Anything above 30 is hot. :)

It's worth noting as well that it works in reverse, too (however obvious it might be to most people).

So if it's 62 degrees F, and you want to your European house-guest what that means in language with which she's most familiar, you can simply think: 62 minus 32 = 30, then cut that it *half*, and you get 15. Which is probably close enough.

I use the formula f-32/9=c/5 or then my Nokia E51 cell phone which has a converter..
