The standard approach would be to subtract 32 from the temperature in Fahrenheit, and then multiply the result by 5/9, which is the same as multiplying by 5 and then dividing by 9. The reason for this is that 32 degrees Fahrenheit is the same as 0 degrees Celsius, and the "size" of each Fahrenheit degree is 5/9 Celsius degrees.
