You're standing in your kitchen, hovering over a tray of puff pastry or maybe a piece of salmon, and the recipe suddenly demands 220 C. If you live in the United States, your oven dial doesn't speak that language. You need the Fahrenheit equivalent, and you need it before the oven preheats to the wrong setting and ruins dinner.
Basically, 220 C is 428 F.

Most people just round it up to 430 F or down to 425 F. Does it matter? Honestly, it depends on what you're baking. If you are roasting root vegetables, a couple of degrees won't kill the vibe. But if you're working with delicate French pastry where the steam needs to hit at a precise moment, those tiny gaps in temperature can be the difference between a flaky masterpiece and a soggy disappointment.
The Quick Math Behind 220 C to F
You probably don't want a math lesson while the kitchen timer is ticking, but knowing the formula helps when your phone isn't handy. To get from Celsius to Fahrenheit, you take the Celsius temperature, multiply it by 1.8, and then add 32.
Let's do the numbers for this specific case. First, you take 220 and multiply it by 1.8, which gives you 396. Then, you add 32. The result is exactly 428.
$$220 \times 1.8 + 32 = 428$$
It’s a weird number. Most American ovens move in increments of 5 or 10 degrees. You’ll likely have to choose between 425 F and 430 F. My advice? Go with 425 F for longer roasts and 430 F if you’re looking for a quick sear or that "shatter-crisp" crust on a pizza.
Why 220 C is the Magic Number for Roasting
In the culinary world, 220 C is often referred to as a "hot" or "very hot" oven. It’s significantly higher than the standard 180 C (350 F) used for cookies and cakes. When a recipe calls for this heat, it’s usually trying to trigger the Maillard reaction as fast as possible. This is the chemical reaction between amino acids and reducing sugars that gives browned food its distinctive flavor.
Think about roasted potatoes. If you cook them at 350 F, they get soft. They’re fine, but they aren't exciting. At 428 F (220 C), the outside dehydrates rapidly, the sugars caramelize, and you get that golden-brown crunch while the inside stays fluffy. Professional chefs like Kenji López-Alt from Serious Eats often advocate for these higher temperatures to achieve texture contrasts that lower heat just can't manage.
The Pizza Paradox
If you’re making homemade pizza, 220 C is actually the bare minimum. Most domestic ovens in Europe max out around this range, which is why European recipes often cite it. However, in the States, many ovens can hit 500 F or 550 F. If your recipe says 220 C for pizza, it’s basically telling you to "crank it up."
Common Conversions You’ll Need
Since you're already checking for 220 C, you'll probably run into these other common European oven settings. It’s helpful to have a mental map of how these translate so you aren't constantly wiping flour off your hands to check Google.
- 140 C is roughly 275 F (Slow cooking territory)
- 160 C is roughly 320 F (Fan-assisted baking)
- 180 C is roughly 350 F (The "Standard" setting)
- 200 C is roughly 400 F (High-heat roasting)
- 220 C is 428 F (The "Blast" heat)
- 240 C is roughly 475 F (Intense searing)
Fan vs. Conventional Ovens
Here is where it gets tricky. If you see a recipe from the UK or Australia calling for 220 C, they might be talking about a "conventional" oven. If you have a convection oven (one with a fan), you usually need to drop the temperature by 20 degrees Celsius.
So, if the recipe says 220 C (Conventional), and you’re using a fan oven, you should actually set it to 200 C. That translates to about 400 F. If you leave it at 428 F with the fan running, you’re likely going to burn the outside of your food before the middle is even warm. Fans circulate hot air, which strips away the "cold" boundary layer of air surrounding the food, making the heat transfer way more efficient. It's basically wind chill, but for your chicken.
Is Your Oven Lying to You?
Most kitchen appliances are not precision instruments. A study by America's Test Kitchen found that many home ovens can be off by as much as 25 degrees Fahrenheit. This means even if you perfectly convert 220 C to 428 F, your oven might actually be hovering at 400 F or spiking to 450 F.
This is why expert bakers use oven thermometers. They cost about ten bucks and sit right on the rack. If you’re serious about hitting that 220 C mark, don't trust the digital display on your stove. Trust the analog thermometer sitting inside.
Real-World Application: What to Cook at 220 C
You’ve got the number. Now, what do you do with it?
- Yorkshire Puddings: These require a massive hit of heat to rise. If the oil isn't screaming hot (220 C territory), they’ll stay flat and sad.
- Puff Pastry: Whether it’s beef wellington or a tart, puff pastry needs the water in the butter to turn to steam instantly. That steam is what pushes the layers apart. 220 C is the sweet spot.
- Whole Roasted Cauliflower: To get those charred, nutty edges without turning the whole thing into mush, high heat is a must.
- Skin-on Chicken Thighs: If you want that skin to render its fat and turn into a cracker-like texture, 428 F is your best friend.
The Actionable Takeaway
Next time you see 220 C in a recipe, don't panic and don't overthink the "8" in 428 F.

- Set your American oven to 425 F if you want to play it safe, or 430 F if you want more browning.
- If your oven has a Convection or Fan setting, drop the target to 400 F.
- Always check the food 5-10 minutes before the timer goes off. High heat moves fast.
- Invest in a cheap oven thermometer to see if your "425 F" is actually what's happening inside the box.
Mastering temperature conversion isn't just about math; it's about understanding how heat interacts with moisture and fat. Now that you know 220 C is roughly 430 F, you can stop scrolling and start cooking.
