A common formula to convert a Fahrenheit temperature (F) to a Celsius temperature (C) is C = 5 9 (F - 32) Solve the temperature for F in terms of C. Show your work. Suppose you use the formula C = 5 9 (F - 32) to convert a Fahrenheit temperature to a Celsius temperature.
To find how many degrees Celsius, divide your number in Fahrenheit by 5/9 (or approximately 0.56), then subtract 32. As an example we'll convert 90 degrees Fahrenheit into Celsius.
C = 5/9f - 32 C = 5/9 x 90 -32 C = 50.4 -32 C = 18.4
