If you’ve ever followed a recipe from another country, you may have paused and wondered: what is 170 degrees Celsius? It’s one of the most common baking temperatures used in recipes worldwide, especially in Europe, Australia, and many professional cookbooks.

Understanding temperature conversions is important because ovens around the world use different measurement systems. Some use Celsius, while others use Fahrenheit. On top of that, fan ovens cook differently from conventional ovens, which can make recipes confusing if you’re unfamiliar with the settings.

In this guide, you’ll learn exactly what 170 degrees Celsius means, how to convert it to Fahrenheit, what it equals in a fan oven, and when this temperature is typically used in cooking and baking.

What Is 170 Degrees Celsius in Fahrenheit?

The simple conversion is:

$\times \frac{9}{5}) + 32 = 338$

So, 170°C equals 338°F.

In most kitchens, people round this number to 340°F for convenience. Many oven dials also use rounded numbers instead of exact temperatures.

This temperature is considered a moderate oven heat, which makes it ideal for baking foods evenly without burning the outside too quickly.

Why 170°C Is a Popular Baking Temperature

Many recipes call for 170°C because it creates balanced heat. It’s hot enough to cook food thoroughly while still allowing baked goods to rise properly.

You’ll commonly see this temperature used for:

Cakes
Muffins
Brownies
Cheesecakes
Cookies
Roasted vegetables
Chicken dishes
Slow-baked casseroles

Professional bakers often prefer moderate temperatures because they help achieve a soft interior and evenly browned exterior.

What Is 170 Degrees Celsius for a Fan Oven?

Fan ovens work differently from conventional ovens. They circulate hot air inside the oven, which cooks food faster and more evenly.

When converting temperatures for a fan oven:

170°C conventional oven is usually about 150°C to 160°C in a fan oven
Most recipes reduce the temperature by around 20°C for fan-assisted cooking

So if a recipe says 170°C and you’re using a fan oven, setting it to approximately 150°C fan is often recommended.

This adjustment helps prevent overcooking or drying out baked foods.

Understanding Conventional vs Fan Oven Temperatures

One reason recipes can seem confusing is because oven types vary by country and manufacturer.

Conventional Oven

A conventional oven uses heating elements without circulating air. Heat tends to concentrate at the top or bottom.

Fan Oven

A fan oven spreads heat evenly using a built-in fan. Because heat circulation is more efficient, foods cook faster.

That’s why fan ovens typically need:

Lower temperatures
Slightly shorter cooking times

If you regularly bake, learning these differences can dramatically improve your results.

Quick Celsius to Fahrenheit Conversion Formula

If you want to convert temperatures yourself, use this formula:

$\times \frac{9}{5}) + 32$

To convert Celsius into Fahrenheit:

Multiply the Celsius temperature by 9
Divide by 5
Add 32

For 170°C:

170 × 9 = 1530
1530 ÷ 5 = 306
306 + 32 = 338°F

Once you use the formula a few times, temperature conversions become much easier.

Foods Commonly Cooked at 170°C

A moderate oven temperature works for many different recipes. Here are some common examples.

Cakes and Cupcakes

Sponge cakes and cupcakes bake beautifully at 170°C because the heat allows them to rise gradually without cracking.

Brownies

Brownies baked at this temperature usually develop soft centers and slightly crisp edges.

Cheesecakes

Cheesecakes benefit from gentler heat to avoid splitting or drying out.

Roasted Vegetables

Vegetables roast evenly while keeping moisture inside.

Chicken and Meat Dishes

Certain slow-roasted meat recipes use 170°C to create tender results without burning the surface.

Is 170°C High or Low Heat?

170°C is generally considered moderate heat.

Here’s how oven temperatures are commonly categorized:

Low heat: 120°C–150°C
Moderate heat: 160°C–180°C
High heat: 190°C–220°C+

Because 170°C sits in the middle range, it’s extremely versatile for everyday cooking.

Tips for Baking at 170°C

To get the best results at this temperature, keep these practical tips in mind.

Preheat the Oven

Always allow the oven to fully preheat before placing food inside.

Use the Middle Rack

The middle rack usually provides the most even heat distribution.

Avoid Opening the Door Too Often

Opening the oven door releases heat and can affect baking consistency.

Check Early in Fan Ovens

Fan ovens often cook faster, so start checking food a few minutes earlier than the recipe suggests.

Use an Oven Thermometer

Many ovens run hotter or cooler than displayed. A thermometer helps ensure accurate baking temperatures.

Why Different Countries Use Celsius and Fahrenheit

Temperature scales vary around the world.

Most countries use Celsius for cooking because it aligns with the metric system. However, the United States still commonly uses Fahrenheit in recipes and household ovens.

That’s why international recipes often require quick conversions.

Understanding both systems makes cooking from global recipes much easier and more enjoyable.

Common Temperature Comparisons Near 170°C

To better understand where 170°C fits, here are nearby temperatures people often use:

160°C = 320°F
170°C = 338°F
180°C = 356°F
190°C = 374°F

These temperatures are among the most frequently used in baking.

FAQs
