When following baking recipes from around the world, you’ll often find oven temperatures listed in different formats — Celsius, Fahrenheit, or gas mark settings. This often leads to a common question for home cooks and bakers: are ovens usually Celsius or Fahrenheit?
Understanding how to convert between these units — and how fan (convection) ovens differ from conventional ovens — can help you achieve consistent, professional baking results every time.
Let’s explore oven temperature standards, an oven chart temperature conversion, oven types, and recommended cooking temperatures for different foods.
1. Are Ovens Usually Celsius or Fahrenheit?
Whether ovens are set in Celsius or Fahrenheit depends largely on where you live:
-
Celsius (°C) is commonly used in the UK, Europe, Australia, and most of Asia
-
Fahrenheit (°F) is standard in the United States and a few other regions
-
Gas Mark settings are mainly used in older UK ovens
Modern ovens often allow you to switch between Celsius and Fahrenheit in the control panel, but many recipes still list only one format. This is why using an oven chart temperature conversion is essential when cooking international recipes.
2. Understanding Oven Types
Before diving into conversion charts, it’s important to understand your oven type, as it affects both temperature accuracy and cooking performance.
Conventional Oven
A conventional oven uses top and bottom heating elements without air circulation. Heat distribution can be uneven, so tray placement matters.
Convection (Fan) Oven
A convection or fan oven uses a built-in fan to circulate hot air evenly. Food cooks faster and more evenly, often at a lower temperature.
Conversion rule of thumb:
-
Reduce temperature by 20°C (25°F) when using a fan oven
-
Increase temperature by 20°C (25°F) when switching to a conventional oven
Example:
-
180°C fan = 200°C conventional
-
350°F convection = 375°F conventional
3. Oven Chart Temperature Conversion (Celsius, Fahrenheit & Gas Mark)
Using an oven chart temperature conversion helps ensure accuracy when switching between regions, oven types, or recipes.
Quick reference examples:
-
160°C = 320°F = Gas Mark 3
-
180°C = 356°F = Gas Mark 4
-
200°C = 392°F = Gas Mark 6
-
220°C = 428°F = Gas Mark 7
Tip:
When converting between convection and conventional ovens, adjust by ±20°C (±25°F) for best results.
4. Common Oven Temperature Ranges
For Meats & Seafood
-
Salmon / white fish: 180–200°C (356–392°F)
-
Shrimp: 190°C (374°F)
-
Squid: 220°C (428°F)
-
Chicken wings: 180°C (356°F)
-
Chicken breast: 210°C (410°F)
-
Steak: 180°C (356°F)
For Pastries & Baked Goods
-
Sponge cake: 200°C (392°F)
-
Puff pastry: 210°C (410°F)
-
Macarons: 190°C (374°F)
-
Cookies: 190–200°C (374–392°F)
-
Cheesecake: 190°C (374°F)
-
Scones: 200°C (392°F)
-
Toasted bread: 180°C (356°F)
For Vegetables & Roasting
-
Garlic cloves: 210°C (410°F)
-
Sausages: 220°C (428°F)
These are general guidelines — always check your recipe and adjust based on oven type.
5. Types of Ovens Explained
By Size
-
Small ovens (10–20L): Fast heating, ideal for small households
-
Medium ovens (20–40L): Balanced size for family cooking
-
Large ovens (40L+): Built-in models for frequent or batch baking
By Function
-
Standard oven: Upper and lower heating elements
-
Air fry oven: Convection cooking with crisp results
-
Steam oven: Adds moisture, ideal for bread and fish
-
Smart oven: App or voice-controlled temperature management
-
Self-cleaning oven: Heat or steam cycles for easy maintenance
6. Oven Temperature Conversion Tips
-
Always preheat your oven before baking
-
Use an oven thermometer — many ovens vary by ±10°C
-
Rotate trays in conventional ovens for even baking
-
Lower temperature slightly when using convection to prevent over-browning
