Whether you’ve got a built-in oven, a range or a mini-oven, making sure your oven temperature is just right is essential for recipe success. Following recipe steps can be a leap of faith at the best of times, so to get the best results, making sure your cooking temp is just right is crucial. Everybody wants that perfect roast dinner, or beautifully brown buns and not blackened bread.

But recipes use different measurements – cups instead of mls and grams. And Fahrenheit instead of Celsius. Trying to work out the difference mid-cook may leave you flustered.

How to convert oven temperatures

So that’s why we’re here to help you navigate the often-confusing world of oven temperatures. Whether you need to switch from F to C or vice versa, or if you're trying to tell gas marks from fan-assisted oven temperatures, here’s our handy cheat sheet.

Oven temperature conversion chart: Fahrenheit, Celsius, Gas Mark, and Fan Assisted Oven

Sometimes, you might find a recipe that uses different temperature scales, like gas marks or fan-assisted oven temperatures. Here's a handy conversion chart to help you make sense of it all:

Celsius (°C) Fan Oven Fahrenheit (°F) Gas Mark
130°C 110°C 250°F 1/2
140°C 120°C 275°F 1
150°C 130°C 300°F 2
170°C 150°C 325°F 3
180°C 160°C 350°F 4
190°C 170°C 375°F 5
200°C 180°C 400°F 6
220°C 200°C 425°F 7
230°C 210°C 450°F 8
240°C 220°C 475°F 9

And in case you’re wondering, yes it’ll work just the same for electric ovens and gas ovens!

How to convert Fahrenheit to Celsius

If you’re reading a recipe from the USA, chances are that the oven temperature will be on the Fahrenheit scale.

You can convert Fahrenheit to Celsius manually. Subtract 32 from the temperature in Fahrenheit, then multiply the result by 5/9. For example, if a recipe states 350°F, the Celsius equivalent is (350 - 32) × 5/9, which equals approximately 176.67°C. Simple, right?

Not really.

So, there are two ways you can do it. Either use an online calculator, or just use our conversion chart above. The fact is that most oven temperatures are pretty standard – so you don’t need to do any insanely complicated math.

For example, lots of recipes will tell you to set your oven to 180°C which is roughly 360°F (actually 356°F). And because you will probably only need to know a few settings, you’ll soon get used to what they translate to.

How to convert Celsius to Fahrenheit

Now, let's reverse the process for those who measure in Celsius and want to convert to Fahrenheit. To do this, multiply the temperature in Celsius by 9/5, then add 32 to the result. For instance, if your recipe lists a temperature of 180°C, the Fahrenheit conversion is (180 × 9/5) + 32, which equals approximately 356°F.

Or you can cheat with an online calculator or use our conversion chart above.

Whichever route you take, understanding oven temperature conversions doesn't have to be a source of stress in the kitchen. Now you can convert Fahrenheit to Celsius to gas marks to fan-assisted oven temperatures, you're ready to get your recipes just right. Happy converting!
