Here's a question for all you math-minded folks out there.Question:
At what point does fahrenheit equal celsius?
Take a guess....
Now scroll down for the answer
Answer: -40 degrees.
You have to know the formula to figure out how to convert celsius to fahrenheit. Most of us haven't done algebra for a while but it's: Fahrenheit = Celsius X 9/5 + 32.
Or t(F) = t(C)x 9/5 +32
t-9t/5 = 32
-4t/5 = 32
t= -40 (so that's the temperature where t(F) = t(C)x 9/5 + 32
