🍳 Cooking Temperature Converter
Convert cooking and oven temperatures between Celsius (°C), Fahrenheit (°F), Gas Mark, and Fan Oven (Convection) settings. Includes common baking, roasting, and slow cooking temperature references.
What Is a Cooking Temperature Converter?
A cooking temperature converter helps you convert oven and cooking temperatures between different scales used in recipes around the world. Different countries and cookbooks use different temperature scales, and getting the temperature right is essential for successful baking and roasting.
This converter supports:
- Celsius (°C): Used in most countries, including the UK, Europe, and Australia.
- Fahrenheit (°F): Commonly used in the United States.
- Gas Mark: A temperature scale used on gas ovens in the UK, Ireland, and some Commonwealth countries.
- Fan Oven (°C): Convection oven temperatures, which are typically 20°C lower than conventional ovens.
How to Convert Cooking Temperatures
The conversion formulas are:
Celsius to Fahrenheit: °F = (°C × 9/5) + 32
Fahrenheit to Celsius: °C = (°F − 32) × 5/9
Gas Mark to Celsius: °C = (Gas Mark × 14) + 121
Celsius to Gas Mark: Gas Mark = (°C − 121) / 14
Fan Oven: Fan temperature = Conventional temperature − 20°C
For example, to convert 180°C (a common baking temperature) to Fahrenheit and Gas Mark:
°F = 180 × 9/5 + 32 = 350°F
Gas Mark = (180 − 121) / 14 = 4
Fan Oven = 180 − 20 = 160°C
Why Use This Converter?
- Instant results: Convert cooking temperatures between all four scales in real-time.
- Gas Mark support: Perfect for UK and Commonwealth recipes using gas ovens.
- Fan oven adjustment: Automatically shows the fan oven equivalent.
- Heat level descriptions: See whether your temperature is "Cool," "Moderate," or "Hot."
- Free & private: No registration, no data storage , all calculations are done in your browser.
❓ Cooking Temperature Converter FAQ
What is Gas Mark on an oven?
Gas Mark is a temperature scale used on gas ovens in the United Kingdom, Ireland, and some Commonwealth countries. Gas Mark 1 is approximately 275°F (135°C), and each step increases by about 25°F (14°C).
How do I convert Celsius to Gas Mark?
Use the formula Gas Mark = (°C − 121) / 14. For example, 180°C → (180 − 121) / 14 = 4.2, which is approximately Gas Mark 4.
What is the difference between conventional and fan ovens?
Fan (convection) ovens circulate hot air, cooking food faster and more evenly. For this reason, you should typically reduce the temperature by 20°C (35°F) when using a fan oven compared to a conventional oven.
What temperature is Gas Mark 4 in Celsius and Fahrenheit?
Gas Mark 4 is approximately 180°C or 350°F. This is the classic moderate baking temperature for cakes and cookies.
What temperature is 350°F in Celsius and Gas Mark?
350°F is approximately 180°C and Gas Mark 4. This is one of the most common baking temperatures.
What does "slow oven" or "moderate oven" mean?
These are descriptive terms for oven temperature ranges: Slow/Cool (140–150°C / 275–300°F / Gas 1–2), Moderate (160–180°C / 325–350°F / Gas 3–4), Hot (200–220°C / 400–425°F / Gas 6–7), and Very Hot (230–240°C / 450–475°F / Gas 8–9).
How accurate is this converter?
This converter provides highly accurate results using the standard conversion formulas. Gas Mark values are approximate as oven dials use rounded numbers.
Is this converter free?
Yes, this converter is completely free to use. No registration or personal data storage is required.
What is the best temperature for baking cakes?
Most cakes bake well at 180°C (350°F, Gas Mark 4). For fan ovens, use 160°C.
What is the best temperature for roasting meat?
For roasting, temperatures typically range from 160–200°C (325–400°F, Gas 3–6) depending on the meat and desired doneness.
