Understanding Oven Temps
Key concepts for consistent baking results
The Conversion Formula
To convert manually: multiply the Celsius temperature by 1.8 (or 9/5), then add 32. For example, 180°C × 1.8 + 32 = 356°F (rounded to 350°F).
What is a Gas Mark?
Gas Marks are a standard temperature scale used on gas ovens in the UK and Ireland. Gas Mark 4 is the most common, equating to 180°C or 350°F.
Fan Oven Adjustments
Fan-assisted ovens circulate hot air, cooking food faster. As a rule of thumb, reduce the standard recipe temperature by 20°C (or 25°F) when using the fan setting.
Verify with a Thermometer
Domestic oven dials can be inaccurate by 10°C to 20°C. Investing in a cheap, independent oven thermometer guarantees your temperature is exactly right.

Oven Converter FAQ
Answers to the most frequently asked questions about converting oven temperatures for baking and cooking.
To convert Celsius to Fahrenheit, multiply the Celsius temperature by 9/5 (or 1.8) and then add 32. For example, 180°C × 1.8 + 32 = 356°F. In practice, this is typically rounded to the nearest 5 or 10 degrees (350°F) to match standard oven dials.
180°C is equivalent to 350°F and Gas Mark 4. This is considered a ‘Moderate’ oven temperature and is the most common setting for baking standard cakes, cookies, and roasting meats.
Yes. Fan-assisted ovens circulate hot air, cooking food faster and more evenly. As a general rule, reduce the standard Celsius temperature by 20°C (or 25°F) when using a fan oven setting to prevent over-browning or drying out.
Domestic ovens can often be inaccurate by 10°C to 20°C due to poor calibration or worn seals. Using an independent, hanging oven thermometer is the best way to verify your oven’s true internal temperature and ensure consistent baking results.
If you are converting the temperature accurately, the cooking time should remain roughly the same. However, if you are deliberately changing the temperature (e.g., cooking multiple dishes at different temps), you will need to monitor the food closely and adjust the time accordingly.
