To convert a temperature from Celsius (°C) to Fahrenheit (°F), use the following formula:
(°C x 9/5) + 32 = °F
This formula involves multiplying the temperature in Celsius by 9/5 and then adding 32 to the result to get the temperature in Fahrenheit.
For example, to convert 20°C to Fahrenheit:
(20 x 9/5) + 32 = 68°F
Therefore, 20°C is equal to 68°F.
