Twenty-eight degrees Celsius is 82.4 degrees Fahrenheit. To convert a temperature from Celsius to Fahrenheit, multiply the temperature by 1.8, and then add 32 to get the final answer.
The formula for converting a temperature from Celsius to Fahrenheit is F = (9/5)C + 32. "F" stands for the number of degrees Fahrenheit. "C" stands for the degrees in Celsius. The fraction 9/5 is equal to 1.8. The equation to convert degrees Fahrenheit into Celsius is: C = (5/9) (F - 32). The temperature scales Celsius and Fahrenheit intersect at minus 40 degrees, which is the same temperature in both scales.
