How this is calculated
°C = (°F − 32) × 5 ÷ 9, and °F = °C × 9 ÷ 5 + 32. Recipes round these, so 350 °F becomes 180 °C.
Fan (convection) ovens cook hotter, so recipes set them about 20 °C (25 °F) lower. Gas mark 1 is 275 °F and each mark adds 25 °F. The chart uses the Celsius values found in most UK recipes, so gas mark 3 is listed as 170 °C rather than the exact 163 °C.
