20 degrees Celsius to degrees Fahrenheit
20 degrees Celsius = 68 degrees Fahrenheit
Formula: degrees Fahrenheit = (degrees Celsius x 9/5) + 32
Twenty degrees Celsius is comfortable room temperature, and converting it to Fahrenheit helps US readers set thermostats and interpret European weather reports.
How to Convert degrees Celsius to degrees Fahrenheit
Celsius and Fahrenheit are related by an affine formula, not a simple multiplication, because their zero points differ. Fahrenheit equals Celsius multiplied by 9/5 and then increased by 32. The two scales read the same only at minus forty degrees.
The formula is degrees Fahrenheit = (degrees Celsius x 9/5) + 32. Apply the formula to 20 degrees Celsius: 20 x 9/5 = 36, then 36 + 32 = 68 degrees Fahrenheit.
The reverse is just as direct: 68 degrees Fahrenheit equals 20 degrees Celsius. That symmetry is a quick way to sanity-check any conversion you make.

Frequently Asked Questions
What is 20 degrees Celsius in degrees Fahrenheit?
20 degrees Celsius equals 68 degrees Fahrenheit. You multiply by 9/5 and add 32 to get there, because the two scales start from different zero points and so are not simply proportional.
Why does temperature need an extra add or subtract?
Because the scales are offset, not just stretched. Each has a different zero, so you must scale and then shift. The single point where both scales show the same number is minus forty degrees, a useful sanity check.
What is 68 degrees Fahrenheit back in degrees Celsius?
