The metric system temperature is the Celsius scale. The Celsius scale uses zero degrees as the freezing point of water and 100 degrees as water's boiling point. In America, however, most people use the Fahrenheit system, so some thermometers do not measure in degrees Celsius. Therefore, if you have a temperature in degrees Celsius, you need to convert it to Fahrenheit to compare it to temperatures recorded in America.
Multiply 180 degrees Celsius by 9 to get 1,620.
Divide 1,620 by 5 to get 324.
Add 324 to 32 to find 180 degrees Celsius equals 356 degrees Fahrenheit.
