Recipes usually round to the nearest common setting, which is why 350 F is written as 180 C and not 177 C. Gas mark 3 is shown as 165 C here, but some charts use 160 C or 170 C, so follow your recipe if it gives a value.
Fan ovens and real oven temperatures
A fan oven moves hot air around, so food often cooks faster. Many UK and European recipes suggest lowering the temperature by about 20 C. Home ovens can also run hotter or cooler than the dial says, and an oven thermometer will show you the truth.
