Here I got a conversion chart of cooking temperature for reference or guide...
As a rule of thumb Celsius is roughly half the Fahrenheit temperature.
Fan assisted ovens are usually set approximately 25 degrees Celsius (i.e. approximately 50 degrees Fahrenheit) lower than others and cooking time is reduced by 10 minutes for every hour of cooking time.
