Bear in mind that this is a guide only and not exact conversions. As a rule of thumb Celsius is approximately half the Fahrenheit temperature. Fan assisted ovens are usually set approximately 25 degrees Celsius (approximately 50 degrees Fahrenheit) lower than non fan assisted and cooking time is reduced by 10 minutes for every hour of cooking time. Different manufacturers and oven types do vary, so always refer to your cooker instruction book if you have it. | |||
