How the Oven Temperature Converter Works
This calculator lets you instantly convert oven temperatures between Celsius, Fahrenheit, and Gas Mark, the three systems used in recipes around the world. It is indispensable when following American (°F), British (Gas Mark), or European (°C) recipes.
Conversion Formulas
- Celsius to Fahrenheit: °F = °C x 9/5 + 32
- Fahrenheit to Celsius: °C = (°F - 32) x 5/9
- Gas Mark: follows a fixed table, not a linear formula
Gas Mark Reference Table
| Gas Mark | °C | °F | Description |
|---|---|---|---|
| 1 | 140 | 275 | Very low |
| 2 | 150 | 300 | Low |
| 3 | 170 | 325 | Moderately low |
| 4 | 180 | 350 | Moderate |
| 5 | 190 | 375 | Moderately hot |
| 6 | 200 | 400 | Hot |
| 7 | 220 | 425 | Very hot |
| 8 | 230 | 450 | Extremely hot |
| 9 | 240 | 475 | Maximum |
Most Common Cooking Temperatures
- 320°F / 160°C / Gas 3: slow cooking, stews, cheesecake
- 350°F / 180°C / Gas 4: the universal temperature for cakes and desserts
- 400°F / 200°C / Gas 6: roasts, vegetables, focaccia
- 425°F / 220°C / Gas 7: bread, pan pizza
- 475°F / 250°C / Gas 9: pizza, quick gratins
Conventional vs. Convection Oven
The convection (fan-assisted) oven requires about 25°F (15-20°C) less than a conventional oven because the fan distributes heat more efficiently. If a recipe says 350°F without specifying, it usually means conventional.
