How to Convert Celsius to Fahrenheit

Quickly convert a temperature from Celsius to Fahrenheit in your head
by Updated January 29, 2009

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.

To find a precise conversion of Celsius to Fahrenheit using Google or Yahoo, type in the following as your search query: Convert 30 degrees Celsius to Fahrenheit

Remember to keep in mind that Water freezes at 0 degrees Celsius or 32 degrees Fahrenheit, and it boils at 100 degrees Celsius or 212 degrees Fahrenheit.
