I'm not understanding the whole degrees celsius= 5/9 ( degrees celsius - 32).
Is there any other way that this can be explained? A more simpler way?
Say I need to change 77 degress farenhiet. How would I go about changing that to degrees celsius?
Establish the Facts.
Celsius
Freezing = 0º
Boiling = 100º
Farenheit
Freezing = 32º
Boiling = 212º
Establish the Model. I believe it to be linear
ºC = B*(ºF - A)
Apply the Facts
0ºC = B*(32ºF - A)
100ºC = B*(212ºF - A)
Solve for the Model Parameters
I will leave this to the interested student. That would be you.
Hint: From the first equation, the value of A should be relatively obvious.
Check with Other Known Values
It is widely known that -40ºC = -40ºF and not quite so widely known that 40ºC = 104ºF. Make sure your values work for these two.
Exploration: Once you get A and B, solve the Model Equation for ºF and create the formula for conversion in the other direction. It will be fun!
