Question:

I just know how to do problems with fahrenheit or celcius. Could you show me step by step how to do these? Then I can do it if you can show me each step of the way.

Hi Doris. Celsius and Fahrenheit are just two scales that measure the
same thing: temperature. There are two differences:

a) the size of the units. 1 degree Fahrenheit is 5/9 of a degree Celsius.
b) where Zero is. 0 degrees celsius is 32 degrees Fahrenheit.

Now to convert between them, we just use these two.

(Temperature in Fahrenheit - 32 ) (5/9) = temperature in Celsius.

for example

212 degrees Fahrenheit is ( 212 - 32 ) (5/9) = 100 degrees Celsius.

(Temperature in Celsius) (9/5) + 32 = temperature inFahrenheit.

for example

0 degrees Celsius is 0 (9/5) + 32 = 32 degrees Fahrenheit.

In fact, the celsius scale was chosen because it makes things simple:
the freezing point of water is 0 and the boiling point is 100. Easier
numbers to remember than 32 and 212 in my opinion!

PS: Here in Saskatchewan, Canada, our winter temperature sometimes
reaches -40 degrees! At that temperature, whether you use Fahrenheit
or Celsius doesn't matter. Can you see why? :)
