How it works
°F = °C × 9/5 + 32; Gas Mark ≈ (°F − 300) ÷ 25 (approximate UK scale)Frequently Asked Questions
What is Gas Mark 4 in Fahrenheit and Celsius?
Gas Mark 4 is about 350°F (180°C) — a very common 'moderate oven' setting for cakes and general baking. Each Gas Mark step is roughly 25°F (about 14°C).
How do I convert a US recipe's Fahrenheit to Celsius for my oven?
Subtract 32, then multiply by 5/9: 375°F becomes (375−32)×5/9 ≈ 191°C, usually rounded to 190°C or 200°C on a dial. Fan (convection) ovens often run about 20°C cooler than the stated conventional temperature.
What does 'moderate oven' or 'hot oven' mean in older recipes?
Older recipes often used descriptive terms: slow ≈150°C/300°F, moderate ≈180°C/350°F, hot ≈200-220°C/400-425°F, very hot ≈230°C+/450°F+. This calculator shows the numeric equivalent for any input.
