About this calculator
Convert an oven temperature between Celsius, Fahrenheit and UK Gas Mark, so a British, American or Indian recipe works in your oven.
Fan or convection ovens run hotter: reduce the temperature by about 20°C (25°F).
How to use it
- Enter the temperature.
- Choose the unit you have.
- Read the other two.
The conversions
°F = °C × 9/5 + 32, and °C = (°F − 32) × 5/9. Gas Mark is a stepped scale: Mark 1 is 140°C (275°F) and each mark above adds about 14°C (25°F) up to Mark 9 at 240°C (475°F). Recipes round to the nearest 5 or 10 degrees.
Worked example
Common settings
| 140°C / 275°F | Gas Mark 1 (very slow) |
| 160°C / 325°F | Gas Mark 3 (slow) |
| 180°C / 350°F | Gas Mark 4 (moderate, most cakes) |
| 200°C / 400°F | Gas Mark 6 (hot) |
| 220°C / 425°F | Gas Mark 7 (breads, pizzas) |
| 240°C / 475°F | Gas Mark 9 (very hot) |
Tips and common mistakes
- Preheat for 15 to 20 minutes.
- Use an oven thermometer; many ovens are off by 10 to 25°C.
- Lower fan-oven settings by 20°C.
- Rack position changes browning.
- Don't open the door during the first half of baking.
