Frequently Asked Questions
What is Gas Mark?▾
Gas Mark is a UK oven temperature scale used in older gas ovens. Gas Mark 1 = 275°F (135°C), each mark adds 25°F (~14°C). Gas Mark 4 = 350°F = 180°C is the most common 'moderate oven' setting.
Why do American recipes use Fahrenheit?▾
USA uses Fahrenheit for everyday measurements. Conversion: °F = (°C × 9/5) + 32. Common: 350°F = 177°C ≈ 180°C, 400°F = 204°C ≈ 200°C.
Are convection oven temperatures different?▾
Yes — convection (fan-forced) ovens cook faster. Reduce conventional oven temperature by 20°C / 35°F when using convection mode, or reduce cooking time by ~25%.
What's a 'moderate' oven?▾
Moderate = 350-375°F (180-190°C, Gas 4-5). It's the most common baking range — cookies, cakes, brownies, casseroles. Lower = slow roasts, higher = pizza & pastry.
Why is my cake undercooked at the recommended temperature?▾
Most home ovens are 25°F (15°C) off from their setting. Use an oven thermometer to verify. Also: dark pans absorb more heat (reduce 25°F), glass pans (lower 25°F), full racks (more crowded = uneven heat).
