What Is 25°C in Fahrenheit?
25 degrees Celsius is 77 degrees Fahrenheit.
How to Convert Celsius to Fahrenheit
To convert degrees Celsius to degrees Fahrenheit, multiply by 9/5, then add 32.
For example: 25 °C × 9/5 = 45, and 45 + 32 = 77 °F.
Where You Meet This Number
A forecast of 25 °C is a warm summer day across most of Europe — pleasant rather than oppressive. It is also the standard reference temperature in chemistry and in electronics datasheets.
A Mediterranean forecast of 25 °C is 77 °F: beach weather without the heat warnings.
What People Get Wrong
Humidity changes what this feels like far more than the number suggests. 25 °C in dry air is comfortable; at 90 percent humidity it feels closer to 86 °F and the body cannot cool itself by sweating.

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.
