Oven Temperature FAQs

What is 350°F in Celsius and Gas Mark?↓
350°F equals 175°C in a conventional oven (or 160°C in a fan-forced convection oven), and corresponds to UK Gas Mark 4.
How do you adjust recipes for a fan-assisted (convection) oven?↓
In a fan-assisted oven, heat distributes more rapidly. Reduce the conventional temperature by 20°C (approx 25°F to 35°F) or decrease the baking time by about 10–15%.
What are the classic oven temperature terms?↓
Slow / Cool oven: 225°F–275°F (Gas 1/4 to 1). Moderate oven: 350°F–375°F (Gas 4 to 5). Hot oven: 400°F–425°F (Gas 6 to 7). Very Hot oven: 450°F–475°F+ (Gas 8 to 9).
