Common Baking Temperatures
Frequently Asked Questions
How do I convert Gas Mark to Celsius?▼
Gas Mark 1 ≈ 140°C (275°F). Each Gas Mark roughly adds 14°C: Gas 2 ≈ 150°C, Gas 3 ≈ 160°C, Gas 4 ≈ 180°C, Gas 5 ≈ 190°C, Gas 6 ≈ 200°C, Gas 7 ≈ 220°C, Gas 8 ≈ 230°C, Gas 9 ≈ 240°C. Gas Mark 4 (180°C/350°F) is the most common baking temperature.
Should I reduce temperature for a fan/convection oven?▼
Yes — reduce the temperature by 20°C (35°F) when using a fan/convection oven. Fan ovens circulate hot air more efficiently, cooking food faster and more evenly. A recipe calling for 180°C in a regular oven becomes 160°C in a fan oven. Some modern ovens auto-adjust when you select fan mode.
Why do UK and US recipes have different temperatures?▼
UK recipes traditionally use Gas Mark or Celsius; US recipes use Fahrenheit. Both systems describe the same physical temperatures — 180°C = 356°F ≈ 350°F, Gas 4. The difference is just units. Confusingly, some older British recipes use Fahrenheit, and many modern US recipes include Celsius.
How do I know if my oven runs hot or cold?▼
Use an oven thermometer — a simple analog dial thermometer placed inside the oven. Set the oven to 350°F (175°C), wait 15 minutes, and compare the reading. Many ovens are off by 25–50°F. Adjust accordingly: if your oven runs 25°F hot, set it 25°F lower than the recipe calls for.
