How to Convert Celsius to Fahrenheit

In the U.S., the base unit of measurement for temperature is Fahrenheit (° F). However, most other countries of the world have adopted the metric system, which uses the Celsius (° C) scale to measure temperature. For converting Celsius to Fahrenheit use this conversion formula: ° F = 9/5 × ( ° C) + 32.

For example:

1. Take the temperature in Celsius and multiply it by 1.8
2. Add 32 degrees
3. The result is degrees Fahrenheit.

To make the conversion quickly in your head, round the numbers 1.8 up to 2 and 32 down to 30. For example: 

1. Take the temperature in Celsius and double it.
2. Add 30 degrees
3. The approximate result is degrees Fahrenheit.

This quick conversion calculation is not as accurate, but the approximation will give you a general idea of the temperature.
