Temperature Conversion

Convert Celsius to Fahrenheit

When converting Celsius to Fahrenheit, it helps to know that, at standard atmosphere, on the Celsius scale, water freezes at 0 degrees, equal to 32 degrees Fahrenheit; and water boils at 100 C (or 212 F).

To convert Celsius temperatures into Fahrenheit:

      1. Multiply the Celsius temperature by 9.
      2. Divide the answer by 5.
      3. Add 32.

Here's the equation:

F = (9/5) C + 32

Convert Fahrenheit to Celsius

To convert Fahrenheit temperatures into Celsius (the operations are opposite, in reverse order):

      1. Subtract 32 from the Fahrenheit temperature.
      2. Multiply the answer by 5.
      3. Divide the answer by 9.

Here's the equation:

C = (F-32) x (5/9)

Here is an automatic F-to-C converter.
