Oven Temperature Conversions: Fahrenheit, Celsius & Gas Mark
Picture this: you find the perfect recipe online, get all your ingredients prepped, and then realize the oven temperature is in Celsius or Gas Mark instead of Fahrenheit.
Set the wrong temp, and you'll end up with a dry cake or cookies that are burnt on the outside and raw in the middle. Let's make sure that doesn't happen. Here is how to easily translate oven temps and adjust for different types of ovens.
Quick Cheat Sheet: Common Oven Temps
- ›Low & Slow: 300°F = 150°C = Gas Mark 2
- ›Moderate (Standard Baking): 350°F = 180°C = Gas Mark 4
- ›Hotter (Cookies & Pastries): 375°F = 190°C = Gas Mark 5
- ›High Heat (Roasting & Bread): 400°F = 200°C = Gas Mark 6
- ›Convection (Fan) Rule: Always drop the temperature by 25°F (15°C) if your oven's fan is running.

| 450°F | 230°C | 215°C | 8 | Very Hot / Broil |
How to Adjust for Convection (Fan) Ovens
Convection ovens use a fan to blow hot air around your food as it cooks. This gets rid of cold spots and speeds up how fast heat transfers to your food.
Since fan ovens are much more efficient than old-school static ovens, you can't just use the standard recipe temperature. Here is what you need to do:
What on Earth is a Gas Mark?
If you see "Gas Mark" in a recipe, it means it was likely written in the UK, Ireland, or Australia. Older gas ovens use numbers on the dial instead of temperatures.
The dial starts low at Gas Mark 1/4 (about 225°F / 110°C) and runs up to Gas Mark 9 (about 475°F / 240°C). If your oven uses these numbers, use the chart above to match your dial to the recipe.
