Convert oven temperatures between Celsius, Fahrenheit, gas mark and fan settings.
Fan ovens circulate air, transferring heat faster, so a 20 degree reduction achieves the same cooking rate. Gas marks step in roughly 14 degree increments from mark 1 at 135 Celsius. Ignoring the fan adjustment is the most common cause of over-browned baking, since the surface cooks well ahead of the interior.
