Temperature Conversion

Take the metric unit of temperature and apply the following formula: (C * 9/5) + 32 = F where we use C for degrees Celsius and F for degrees Fahrenheit. If you wish to do a temperature unit conversion from F to C you need to reverse the formula. The result should look like this : (F-32) * 5/9 = C.
