Oven Temperature Tips

  • Preheating: Always preheat your oven for 10-15 minutes before baking for consistent results.
  • Oven thermometer: Oven dials can be inaccurate by 25°F. Use an oven thermometer for precision baking.
  • Convection ovens: Reduce temperature by 25°F (15°C) when using convection/fan settings.
  • Altitude: At high altitudes, baking temperatures may need adjustment.

Temperature Conversion Formulas

Fahrenheit = (Celsius × 9/5) + 32
Celsius = (Fahrenheit - 32) × 5/9
Gas Mark = (Fahrenheit - 225) / 25

Common Baking Temperatures:

  • • 180°C / 350°F / Gas 4 - Cakes and cookies
  • • 200°C / 400°F / Gas 6 - Roasting vegetables
  • • 220°C / 425°F / Gas 7 - Pizza and bread
  • • 160°C / 325°F / Gas 3 - Slow baking

Convection Oven Tip:

  • • Reduce temperature by 25°F (15°C)
  • • 350°F conventional = 325°F convection
  • • 180°C conventional = 160°C convection
  • • Cooking time may also be reduced by 25%

Frequently Asked Questions About Oven Temperatures

What is 180°C in Fahrenheit?

180°C equals 350°F, which is Gas Mark 4. This is the most common baking temperature for cakes, cookies, and many baked goods.

What does Gas Mark mean?

Gas Mark is a temperature scale used on gas ovens in the UK and some Commonwealth countries. Gas Mark 1 is 275°F (140°C), and each increment adds 25°F.

Should I adjust temperature for convection ovens?

Yes. Convection ovens circulate hot air, cooking food faster and more evenly. Reduce the temperature by 25°F (15°C) from conventional oven recipes.

Why do American recipes use Fahrenheit?

The US is one of the few countries still using Fahrenheit for cooking. Most other countries use Celsius. Gas Mark is primarily used in the UK for gas ovens.

How accurate are oven temperature dials?

Oven dials can be off by 25-50°F. For precision baking, use a standalone oven thermometer. It's a cheap tool that can save ruined batches.
