180 degrees Fahrenheit to degrees Celsius
180 degrees Fahrenheit = 82.2222 degrees Celsius
Formula: degrees Celsius = (degrees Fahrenheit - 32) x 5/9
One hundred eighty degrees Fahrenheit is a key cooking and water-heater temperature in the US, and the Celsius figure makes it readable on metric equipment.
How to Convert degrees Fahrenheit to degrees Celsius
Fahrenheit converts to Celsius with an affine formula because the scales have different zero points. You subtract 32 from the Fahrenheit value and then multiply by 5/9. The scales coincide only at minus forty degrees, where both read the same number.
The formula is degrees Celsius = (degrees Fahrenheit - 32) x 5/9. Apply the formula to 180 degrees Fahrenheit: 180 - 32 = 148, then 148 x 5/9 = 82.2222 degrees Celsius.
The reverse is just as direct: 82.2222 degrees Celsius equals 180 degrees Fahrenheit. That symmetry is a quick way to sanity-check any conversion you make.
