US and Metric Equivalents

To convert temperature from degrees Celsius to degrees Fahrenheit:
Multiply by 9,
divide by 5,
and add 32.
To convert temperature from degrees Fahrenheit to degrees Celsius:
Subtract 32,
multiply by 5,
and divide by 9.
Zero degrees Celsius is 32 degrees Fahrenheit, the freezing point of water at Sea Level.
100 degrees Celsius is 212 degrees Fahrenheit, the boiling point of water at Sea Level.
