Converting oven time and temp from convection to conventional
180 fan is 180 degrees Centigrade with the fan on. The general advice when converting from a fan to a non fan oven is increase temperature 15-20 degrees, so the range you are looking for is between 383 and 392 degrees Fahrenheit. If you have a digital stove I'd say set it for 390, if it's a dial you'll need to eyeball it.
