How to convert Celsius to Fahrenheit
The Celsius to Fahrenheit conversion formula is T(°F) = T(°C) × 9/5 + 32. This formula derives from the fact that the Fahrenheit scale has a zero point at -17.78°C and a scaling factor of 1.8.
T(°F) = T(°C) × 9/5 + 32
Multiply the Celsius value by 9/5 (which equals 1.8) and then add 32:
T(°F) = T(°C) × 1.8 + 32
Example
Convert 25°C to Fahrenheit:
T(°F) = 25 × 9/5 + 32 = 45 + 32 = 77°F
