Question

How do you change from Fahrenheit to Celsius for some of us who are Canadians?

Answer 1

Type Fahrenheit to Celsius converter in google and click on one of the results.

Answer 2

If you know the temperature in one of the scales, use this algebraic expression to calculate the other:

F = 1.8C + 32

So if the temperature is 86 degrees Fahrenheit (like it is here at my house today), then it is

86 = 1.8C + 32 (subtract 32)

54 = 1.8C (divide by 1.8)

30 = C

30 degrees Celsius.

Answer 3

Get a life.

Answer 5

('F)=1.8('C)+32

-or-

('C)=(5/9)('F-32)

Answer 6

If F is degrees Fahrenheit and C degrees Celsius, then

C = (F -32) × 5/9

F = 32 + (C × 9/5)

Answer 7

some cellphones have converter..

Answer 8

A?

Answer 9

5/9 times (degrees F - 32)

to convert back, (9/5 times degrees C) + 32

Answer 10

Somewhere on the internet there is a conversion chart. Somewhere in the library there is a conversion chart. Copy either of those and you have solved your problem. We Americans can also do  with some knowledge on converting Fahrenheit to Celsius.

Answer 11

Here's another way to do it in your head that's not completely accurate. Let's say it's 81F to work with an example.

16C = 61F

Figure out the diff btwn 81F & 61F = 20

divide this # by 2 = 10  (You know you divide bc C is on a smaller scale than F)

Add this to 16C 16+10 = 26C (If it was 55F, you would subtract math answer from 16)

55F --> ?C

61-55 = 6

6/2 = 3

16-3 = 13C

20C --> ?F

find difference from 16: 20 - 16 = 4

multiply by 2, 2X4 = 8

add to 61, 61+8 = 69F

Pretty accurate. Once you get the hang of it, it's really simple to do

If you want accuracy, just type in celsius to fahrenheit into google

Answer 12

A simple, yet not always accurate way is as follows... take the Fahrenheit number and subtract 32 and divide by 2 to get the approximate reading in Celsius. So...

70F, minus 32, divided by 2 is 19C.

82F, minus 32, divided by 2 is 25C

It also works in reverse of course...

32C, times 2, plus 32 is 96F

16C, times 2, plus 32 is 64F

These are not 100% accurate and get less accurate when you get into lower temperatures... -40F is actually -40C so in this case it wouldn't work, right!

C = (F -32) × 5/9, that's a new one to me and is far more accurate. That's fantastic, thanks!!

Answer 14

just type it in google and it even might do it for you. Will im from Europe and i sometimes need to convert Fahrenheit as well, so like 30 deggres is about 0 in Fahrenheit.

Answer 15

google a conversion chart for yourself

Answer 16

Celsius=(5/9)*(Fahrenheit-32)

/ = division

* = multiplication

- = subtraction

Answer 17

Celsius x 1.8 = Fahrenheit

Fahrenheit / 1.8 = Celsius

Answer 18

F=1.8(C)+32

Answer 19

Formula   C = (F - 32) x 5/9     F = C x9/5 + 32

Answer 20

Subtract 32 from Farenheit temperature then multiply by 5 and divide by 9 to get Celsius temperature
