If you’ve found a recipe that lists the oven temperature in Celsius, you may be wondering what is 170 degrees Celsius in Fahrenheit. This is one of the most common temperature conversions because many recipes from Europe, Australia, and other countries use Celsius, while ovens in the United States typically display Fahrenheit.
The exact answer is:
170°C = 338°F
For everyday baking, many cooks round this to 340°F, although some ovens only allow settings in 5- or 10-degree increments.
Whether you’re baking cakes, cookies, bread, or roasting vegetables, knowing this conversion helps ensure your food cooks properly.
Quick Answer
| Celsius | Fahrenheit |
|---|---|
| 170°C | 338°F |
| Rounded Oven Setting | 340°F |
Answer: 170 degrees Celsius equals 338 degrees Fahrenheit, which is commonly rounded to 340°F on most home ovens.
How to Convert 170°C to Fahrenheit
You can convert Celsius to Fahrenheit using a simple formula.
Step 1: Multiply by 9
170 × 9 = 1,530
Step 2: Divide by 5
1,530 ÷ 5 = 306
Step 3: Add 32
306 + 32 = 338°F
Final Answer: 170°C = 338°F
Celsius to Fahrenheit Formula
Use this formula whenever you need to convert temperatures.
Fahrenheit = (Celsius × 9/5) + 32
For 170°C:
(170 × 9/5) + 32 = 338°F
This formula works for converting any Celsius temperature into Fahrenheit.
Why Recipes Use Different Temperature Units
The temperature scale used in recipes depends on the country where the recipe was created.
Celsius (°C)
Celsius is commonly used in:
- Europe
- Australia
- New Zealand
- Canada
- Most Asian countries
Fahrenheit (°F)
Fahrenheit is mainly used in:
- United States
- A few Caribbean countries
If you’re using an international cookbook or online recipe, you’ll often need to convert the oven temperature.
Is 170°C a Good Baking Temperature?
Yes. 170°C (338°F) is considered a moderate oven temperature that works well for a wide range of baked and roasted foods.
It’s commonly used for:
- Sponge cakes
- Cupcakes
- Muffins
- Brownies
- Cookies
- Cheesecakes
- Banana bread
- Roasted vegetables
- Chicken breasts
- Baked pasta dishes
This temperature allows food to cook evenly without browning too quickly.
Conventional vs. Fan Oven Temperatures
Fan-assisted (convection) ovens circulate hot air, allowing food to cook more efficiently.
| Oven Type | Temperature |
|---|---|
| Conventional Oven | 170°C (338°F) |
| Fan/Convection Oven | 150–160°C (302–320°F) |
Always check your recipe because fan ovens often require a temperature reduction of 10–20°C.

Real-World Cooking Examples
Baking a Sponge Cake
Many sponge cake recipes call for 170°C, helping cakes rise evenly without over-browning.
Baking Muffins
Muffins bake well at 170°C to 180°C, producing a soft interior and lightly golden tops.
Roasting Vegetables
Carrots, potatoes, zucchini, and peppers roast evenly at 170°C, developing natural sweetness while remaining tender.
Cooking Lasagna
Lasagna often bakes at 170°C to ensure the pasta cooks thoroughly and the cheese melts evenly.
Why Accurate Oven Temperature Matters
Using the correct oven temperature helps achieve consistent cooking results.
Even Baking
Food cooks uniformly from the center to the edges.
Better Texture
Proper temperatures help cakes stay moist and cookies bake with the desired crispness.
Improved Flavor
Correct heat encourages browning and caramelization without burning.
Reliable Results
Following the recommended temperature increases the chances of successfully recreating a recipe.
Common Conversion Mistakes
Confusing Celsius and Fahrenheit
Accidentally setting your oven to 170°F instead of 170°C will result in food cooking far too slowly.
Forgetting to Round
Although 170°C equals 338°F, most home ovens can simply be set to 340°F.
Ignoring Oven Type
Fan ovens typically require lower temperatures than conventional ovens.
Not Preheating
Always allow your oven to fully preheat before placing food inside for even cooking.
Expert Baking Tips
- Preheat your oven for at least 10–15 minutes before baking.
- Use an oven thermometer to verify your oven’s actual temperature.
- Round 338°F to 340°F unless the recipe specifies otherwise.
- Reduce temperatures slightly for convection ovens.
- Avoid opening the oven door frequently, as this can lower the internal temperature.
