About 170°C / 338°F: Temperature Facts and Applications
170°C (338°F) is a moderate oven temperature that sits between the standard baking temperature of 180°C (356°F) and gentle baking temperatures around 160°C (320°F). This makes it versatile for various cooking applications where you want thorough cooking without excessive browning.
At 170°C, many baked goods cook evenly while maintaining moisture. It's particularly good for delicate items like cheesecakes, custards, and fruit cakes that might crack or dry out at higher temperatures. The moderate heat allows the interior to cook completely before the exterior becomes too dark.
In non-culinary contexts, 170°C is used in various industrial processes including certain types of plastic molding, laboratory procedures, and material testing. It's also a common temperature for heat treatment of some metals and for sterilization processes where higher temperatures might damage sensitive materials.
Practical Applications of 170°C (338°F)
170°C (338°F) is ideal for delicate baked goods that need gentle, even heat:
- Cheesecakes: Prevents cracking and ensures creamy texture
- Fruit cakes: Slow baking allows fruits to plump without burning
- Merringues: Dries them out without browning
- Custards: Cooks gently without curdling
This temperature works well for slower roasting methods:
- Tough cuts of meat: Breaks down collagen without drying out
- Root vegetables: Caramelizes natural sugars slowly
- Dehydrating: Perfect for drying herbs and fruits
- Reheating: Warms food thoroughly without overcooking
170°C translates differently in these appliances:
- Air fryers: Equivalent to about 150-160°C due to intense air circulation
- Convection ovens: Typically reduce by 20°C to 150°C
- Fan-forced ovens: Similar to convection ovens
- Gas ovens: May need monitoring as heat distribution varies
Air Fryer Tip
When using 170°C in recipes for air fryers, remember that most air fryers cook faster and more efficiently than conventional ovens. For best results:
- Reduce the temperature by 15-20°C (or 25-35°F)
- Check for doneness 5-10 minutes earlier than the recipe suggests
- Shake or turn food halfway through cooking for even results
Oven Temperature Guide (Fan, Conventional & Fan-Forced)
170°C in Different Oven Types
Oven Type | Adjusted Temp | Best For |
---|---|---|
Conventional Oven | 170°C = 338°F | Delicate baking, slow roasting |
Fan Oven (Convection) | 150°C = 302°F (Reduce by 20°C) | Even baking with reduced temperature |
Fan-Forced (AU/UK) | Same as Fan Oven (150°C) | Term used in Australia/UK |
Gas Oven (Mark) | Gas Mark 3 | Moderate oven setting |
Note: Oven temperatures can vary significantly between models and types. Always refer to your oven's manual for specific guidance, and consider using an oven thermometer for accurate temperature reading.
When to Use 170°C (338°F)?
- Baking - Cheesecakes, custards, delicate pastries
- Slow Roasting - Tough cuts of meat, root vegetables
- Dehydrating - Herbs, fruits, jerky (with door slightly ajar)
- Reheating - Foods that need gentle warming without drying out

FAQs
What is 170°C in Fahrenheit for baking?
170°C converts to 338°F. This is a moderate oven temperature ideal for baking delicate items like cheesecakes, custards, and fruit cakes that need gentle, even heat to cook through without burning or cracking.
What is 170°C in a fan oven?
For fan ovens (convection ovens), you typically reduce the temperature by 20°C. So 170°C in a conventional oven would be approximately 150°C in a fan oven. The Fahrenheit equivalent would be 302°F.
What is 170°C in an air fryer?
Air fryers cook more efficiently than conventional ovens, so you typically need to reduce the temperature by 15-20°C. For recipes calling for 170°C, set your air fryer to around 150-155°C (302-311°F) and check for doneness a few minutes earlier than the recipe suggests.
What gas mark is 170°C?
170°C is equivalent to Gas Mark 3 on a gas oven. Gas Mark 3 is considered a moderate oven temperature, suitable for slow roasting and gentle baking.
Is 170°C hot for baking?
170°C (338°F) is considered a moderate baking temperature. It's cooler than standard baking temperatures (which are typically 180°C/350°F) but warmer than very gentle baking temperatures (150-160°C). It's ideal for items that need thorough cooking without excessive browning.
How do I convert 170°C to Fahrenheit in my head?
A quick mental calculation: Double the Celsius value (170×2=340), then subtract 10% (34) to get 306, and finally add 32 to get 338°F. This gives you the exact conversion of 338°F.
