Celsius to Fahrenheit

The metric system uses the Celsius scale to measure temperature. However, temperatures are still measured on the Fahrenheit scale in the U.S.

  • Water freezes at 0° Celsius and boils at 100° Celsius which is a difference of 100°.
  • Water freezes at 32° Fahrenheit and boils at 212° Fahrenheit which is a difference of 180°.

Therefore each degree on the Celsius scale is equal to 180/100 or 9/5 degrees on the Fahrenheit scale.

How to convert Celsius temperatures to Fahrenheit:

  1. Multiply the Celsius temperature by 9/5.
  2. Add 32° to adjust for the offset in the Fahrenheit scale.
  3. Example: Convert 37° Celsius to Fahrenheit.

\sum 37 \times \frac{9}{5}

37 * 9/5 = 333/5 = 66.6 66.6 + 32 = 98.6o F

   There is a mental math method to convert from Celsius to Fahrenheit. The ratio of 9/5 is equal to 1.8 and 1.8 is equivalent to 2 - 0.2
       * How to convert Celsius temperatures to Fahrenheit with mental math. Double the Celsius temperature (multiply by 2).
       * Take 1/10 of this number (2 * 1/10 = 0.2) and subtract it from the number above.
       * Add 32o to adjust for the offset in the Fahrenheit scale.
       *
       * Example: convert 37o C to Fahrenheit.
         37 * 2 = 74
         74 * 1/10 = 7.4
         74 - 7.4 = 66.6
         66.6 + 32 = 98.6o F
