How To Convert Between Degrees Fahrenheit and Celsius


Converting between Fahrenheit and Celsius temperature scales is useful if you are working temperature conversion problems, work in a lab, or simply want to know how hot or cold it is in a country that uses the other scale! It's easy to make the conversion. One way is to look at a thermometer that has both scales and simply read the value. If you're doing homework or need to do a conversion in a lab, you'll want the calculated values. You can use an online temperature converter or else do the math yourself. Here's what you do:

Celsius to Fahrenheit Degrees

F = 1.8 C + 32
  1. Multiply the Celsius temperature by 1.8.
  2. Add 32 to this number.
  3. Report the answer in degrees Fahrenheit.
Example: Convert 20°C into Fahrenheit.
  1. F = 1.8 C + 32
  2. F = 1.8 (20) + 32
  3. 1.8 x 20 = 36 so F = 36 + 32
  4. 36 + 32 = 68 so F = 68°F
  5. 20°C = 68°F

Fahrenheit to Celsius Degrees

C = 5/9 (F-32)
  1. Subtract 32 from the degrees Fahrenheit.
  2. Multiply the value by 5.
  3. Divide this number by 9.
  4. Report the answer in degrees Celsius.
Example: Convert body temperature in Fahrenheit (98.6°F) to Celsius.
  1. C = 5/9 (F-32)
  2. C = 5/9 (98.6 - 32)
  3. 98.6 - 32 = 66.6 so you have C = 5/9 (66.6)
  4. 66.6 x 5 = 333 so you have C = 333 / 9
  5. 333 / 9 = 37°C
  6. 98.6°F = 37°C
