350°F in Celsius, Gas Mark, and Fan Oven Settings
US recipes give oven temperatures in Fahrenheit (°F). Most other countries set ovens in Celsius (°C), and UK recipes and gas ovens often use Gas Mark. When your recipe and your oven use different scales, you have to convert before you preheat.
Type a temperature in °F or °C and the converter shows the other unit, the nearest Gas Mark, a heat level such as moderate or hot, and the temperature to set on your oven. The exact result for 350°F is 176.7°C, so the tool also shows 180°C, the exact value rounded to the nearest 10°C. Settings in °F are rounded to the nearest 25°F.
It also shows the fan oven temperature (20°C or 25°F lower than the conventional setting). A second tab estimates the bake time when you can't use the recipe's temperature, such as baking a 425°F recipe at 400°F.
Situations Where Oven Temperatures Get Confusing
A US recipe says 350°F
Enter the Fahrenheit temperature to get the Celsius value and the number to set on your oven. One-tap buttons cover common temperatures from 300°F to 450°F.
A UK recipe says Gas Mark 4
Tap a mark in the Gas Mark chart to see its °C and °F values. Entering a temperature does the reverse and shows the nearest mark.
Your oven has a fan setting
See the fan oven temperature for a recipe written for a conventional oven, in both °C (20° lower) and °F (25° lower).
You can't bake at the recipe's temperature
Enter the recipe's temperature and time plus the temperature you'll use to get an estimated bake time. A warning appears if the two temperatures are more than 30°C (54°F) apart.
A recipe just says "moderate oven"
See where a temperature falls on the heat scale, from proofing and warming to very hot, and which range each label covers.
Steps: Convert a Temperature and Adjust the Bake Time
- On the Convert Temperature tab, choose °F or °C and type your temperature, or tap a common one.
- Read the converted temperature, the value to set on your oven, the Gas Mark, and the heat level.
- Using a fan oven? Check the fan oven line for the lower setting.
- Changing the recipe's temperature? Open the Bake Time tab, enter the recipe's temperature and time, then the temperature you'll use.

How the Numbers Are Calculated and Rounded
- Oven setting: °C values are rounded to the nearest 10°C and °F values to the nearest 25°F. If your oven dial uses different steps, pick the closest setting.
- Gas Mark: the tool picks the nearest mark in the chart for temperatures from 100°C to 250°C (212°F to 482°F). Outside that range it shows no Gas Mark. Charts from different publishers can differ slightly.
- Fan oven: the tool subtracts 20°C or 25°F from the rounded oven setting. These are common rules of thumb. If your oven manual gives a different adjustment, follow the manual.
- Bake time: the tool changes the time by the same percentage as the change in temperature, calculated in °C. It is an estimate. Pan material and batter depth also affect results.
- Privacy: calculations run in your browser and nothing is uploaded.

Rounding the decimals.
350°F converts to 176.7°C, but oven dials rarely offer that precision. The "Set oven to" column rounds to the nearest 10°C, which is the value most Celsius recipes use.
Going from °C to °F.
US ovens are usually set in 25°F steps. 180°C is exactly 356°F, but you would set 350°F. In the same way, 200°C (392°F) becomes 400°F and 220°C (428°F) becomes 425°F.
Fan oven column.
The °C figure is the oven setting minus 20°C, and the °F figure is the original °F temperature minus 25°F. Both are rules of thumb. If a recipe already gives a fan temperature, don't subtract again.
Fahrenheit, Celsius, and Gas Mark: What the Numbers Mean
How the three scales relate, how to convert between them, and what to do when your oven or recipe doesn't match.
Fahrenheit to Celsius: (°F − 32) × 5 ÷ 9
To convert Fahrenheit to Celsius, use °C = (°F − 32) × 5 ÷ 9. To convert Celsius to Fahrenheit, use °F = °C × 9 ÷ 5 + 32.
The result is often a decimal, such as 176.7°C for 350°F. For baking, round to the nearest setting your oven offers. That is why Celsius recipes list 180°C for what a US recipe calls 350°F.
Changing the temperature changes the bake time
If you can't use the recipe's temperature, for example because another dish is in the oven, scale the time by the same percentage as the temperature change.
Lowering a recipe from 425°F to 400°F is a drop of about 6%, so a 20-minute bake becomes about 21 minutes. Raising the temperature shortens the time by the same kind of percentage.
Keep the change small. The converter warns you when the two temperatures are more than 30°C (54°F) apart, because the food may rise and brown differently at that point. Recipes that depend on a blast of heat or very gentle heat, such as choux pastry or cheesecake, are the least forgiving.
What Gas Mark means
Gas Mark is a numbered scale from 1/4 to 9 used on many UK gas ovens and in UK recipes. Gas Mark 4 is 180°C (350°F) and Gas Mark 6 is 200°C (400°F).
The number is not a temperature, so don't read Gas Mark 4 as 4°C or 4°F. Use the Gas Mark chart in the converter to translate it.
Fan oven vs. conventional oven
A fan oven (called a convection oven in the US) circulates hot air, so the same temperature can brown food faster than a conventional oven. A common rule of thumb is to set it 20°C lower, or 25°F lower in Fahrenheit.
Check whether your recipe lists separate conventional and fan temperatures. If it does, use the fan number as written. Some oven manuals give their own adjustment, and that takes priority.
Low, moderate, and hot ovens
Recipes that say "moderate oven" don't all agree on exact degrees. This converter uses low: 130–160°C (266–320°F), moderate: 160–200°C (320–392°F), and hot: 200–230°C (392–446°F). Below 100°C (212°F) it shows "proofing & warming", and that range has no Gas Mark.
Common Oven Temperature Mistakes
Typing a Fahrenheit number into an oven set to Celsius
A recipe says 350, and the oven is set to 350°C instead of 350°F. The food burns. The reverse also happens: 180 is entered as °F and the oven runs far too cool.
💡 See the solution▼
Changing the temperature but not the time
You bake a 220°C recipe at 200°C for the full 20 minutes and the center is underdone. Raising the temperature without shortening the time browns the outside too early.
💡 See the solution▼
Using a conventional-oven temperature in a fan oven
A recipe written for a conventional oven is baked in a fan oven at the same temperature, and the edges or tops brown too quickly. Sugary bakes are especially prone to this.
💡 See the solution▼
Reading Gas Mark as a temperature
Gas Mark 4 gets read as 4 degrees, or as a number to enter into a Celsius oven. Gas Mark is its own scale, and the number has no temperature meaning by itself.
💡 See the solution▼
Trusting the dial without checking the oven
Home ovens can run hotter or cooler than the dial says, so a perfectly converted temperature still gives uneven results. This matters more than the decimals in the conversion.

Oven Temperature Questions Answered
Q.What is 350°F in Celsius?
A. 350°F is 176.7°C. Most ovens are set to 180°C, which is also Gas Mark 4. The same approach works for other common temperatures: 325°F is 162.8°C (set 160°C), 375°F is 190.6°C (set 190°C), 400°F is 204.4°C (set 200°C), 425°F is 218.3°C (set 220°C), and 450°F is 232.2°C (set 230°C). The converter shows the exact value and the rounded oven setting together.
Q.What is the formula to convert Fahrenheit to Celsius?
A. Subtract 32 from the Fahrenheit temperature, multiply by 5, then divide by 9: °C = (°F − 32) × 5 ÷ 9. To go the other way, multiply Celsius by 9, divide by 5, and add 32: °F = °C × 9 ÷ 5 + 32. For 350°F that gives (350 − 32) × 5 ÷ 9 = 176.67°C.
Q.Is 180°C the same as 350°F?
A. Almost. 180°C is exactly 356°F, but US ovens are usually set in 25°F steps, so 180°C is normally set as 350°F. The converter does the same rounding: 180°C becomes 350°F, 200°C becomes 400°F, and 220°C becomes 425°F.
Q.What is Gas Mark, and how do I convert it?
A. Gas Mark is the numbered scale on many UK gas ovens and in UK recipes. It runs from 1/4 up to 9. Gas Mark 4 is 180°C (350°F) and Gas Mark 6 is 200°C (400°F). The number is not a temperature, so Gas Mark 4 does not mean 4 degrees. Enter a temperature to see the nearest mark, or tap a mark in the Gas Mark chart to see its °C and °F values.
Q.How do I convert an oven temperature for a fan or convection oven?
A. A common rule of thumb is to set a fan (convection) oven 25°F lower than a recipe written for a conventional oven. In Celsius, the usual rule is 20°C lower. For example, a 350°F recipe becomes 325°F, and a 180°C recipe becomes 160°C. The converter shows both. These are starting points, so follow your oven's manual if it gives a different adjustment, and check the food a little early. If a recipe already lists a fan temperature, use that number as written.
Q.How long should I bake if I change the oven temperature?
A. Enter the recipe's temperature and time, then the temperature you plan to use, on the Bake Time tab. The converter changes the time by the same percentage as the temperature change, calculated in °C. For example, a 20-minute bake at 425°F comes out to about 21 minutes at 400°F, and a 20-minute bake at 220°C comes out to about 22 minutes at 200°C. This is an estimate. Start checking at about 80% of the estimated time.
Q.How much can I change the oven temperature before the recipe stops working?
A. The converter shows a warning when the two temperatures are more than 30°C (54°F) apart. At that point the food may rise, brown, or dry out differently, and changing the time alone cannot make up for it. Stay as close to the recipe's temperature as your oven allows.
Q.Are the numbers I type sent anywhere?
A. No. All calculations run in your browser. The temperatures and times you enter are not uploaded or stored.
