Where You Meet This Number
This is the temperature most offices, hotels and homes are set to, and the one a forecast means by "mild". For an American reader it is the difference between needing a jacket and not.
A forecast of 20 °C and sunny is 68 °F — shirtsleeves weather, no jacket.
What People Get Wrong
The quick trick of doubling and adding 30 gives 70 °F here, which is 2 degrees high. It is fine for deciding what to wear and wrong for a thermostat.

About These Scales
Degree Celsius
The Celsius scale puts the freezing point of water at 0 degrees and its boiling point at 100 degrees at sea level. It is the everyday temperature scale in nearly every country except the United States.
Degree Fahrenheit
On the Fahrenheit scale water freezes at 32 degrees and boils at 212 degrees, so one Fahrenheit degree is 5/9 the size of a Celsius degree. It remains the standard scale for weather, ovens and body temperature in the United States.
