How to Do the Math to Convert Termperatures

To convert Fahrenheit temperatures into Celsius:

  • Begin by subtracting 32 from the Fahrenheit number.
  • Divide the answer by 9.
  • Then multiply that answer by 5.

Here's an example:
Change 95 degrees Fahrenheit to Celsius: (95 - 32)/9*5
95 minus 32 is 63.
Then, 63 divided by 9 is 7.
Finally, 7 times 5 is 35 degrees Celsius.

To convert Celsius temperatures into Fahrenheit:

  • Begin by multiplying the Celsius temperature by 9.
  • Divide the answer by 5.
  • Now add 32.

Here's an example:
Change 20 degrees Celsius to Fahrenheit: 20*9/5 + 32
20 times 9 is 180.
Then 180 divided by 5 is 36.
Finally, 36 plus 32 is 68 degrees Fahrenheit.
