Conversions may appear difficult at first; once you understand the formula needed for the conversion at hand, however, the process is quite simple. To find the Celsius value of a Fahrenheit temperature, use the formula (F - 32) / 1.8. Converting 65 degrees Fahrenheit involves substituting 65 for the F variable.
Continue ReadingIn the case of converting Fahrenheit to Celsius, the equation to use is (F - 32) / 1.8 = C.
Put the Fahrenheit figure into the equation. For this example, F = 65.
To finish the conversion, do the math: 65 - 32 = 33, and 33 / 1.8 = 18.33. Thus, 65 degrees Fahrenheit equals 18.33 degrees Celsius.
