## Celsius to Fahrenheit formula

Celsius (°C) to Fahrenheit (°F), how to convert & conversion table.

## How to convert Celsius to Fahrenheit

The temperature *T* in degrees Fahrenheit (°F) is equal to the temperature *T* in degrees Celsius (°C) times 9/5 plus 32:

*T*_{(°F)} = *T*_{(°C)} × 9/5 + 32

or

*T*_{(°F)} = *T*_{(°C)} × 1.8 + 32

#### Example

Convert 20 degrees Celsius to degrees Fahrenheit:

*T*_{(°F)} = 20°C × 9/5 + 32 = 68 °F
