Understanding Gas Marks

Gas marks are a temperature scale used primarily in the United Kingdom and some Commonwealth countries. The scale typically ranges from 1/4 to 10, with each increment representing approximately 25°F (14°C) difference.

Gas Mark Formula

To convert Gas Mark to Fahrenheit:

°F = (Gas Mark × 25) + 250

Example: Gas Mark 4 = (4 × 25) + 250 = 350°F

Common Uses

  • British and Irish recipes
  • Older gas ovens
  • Traditional cookbooks
  • Some Australian recipes

Note: Modern digital ovens typically use Celsius or Fahrenheit. Gas marks are most commonly found in older gas ovens and traditional British recipes.

Baking Temperature Tips

Low Temperature (250-325°F / 120-165°C)

  • Slow-roasted meats
  • Drying/dehydrating
  • Meringues
  • Keeping food warm

Moderate (325-375°F / 165-190°C)

  • Cakes and cupcakes
  • Cookies
  • Casseroles
  • Baked chicken

Hot (375-425°F / 190-220°C)

  • Roasted vegetables
  • Pies
  • Quick breads
  • Roasted potatoes

Very Hot (425-500°F / 220-260°C)

  • Pizza
  • Bread
  • Broiling
  • Searing

Pro Tip: Always preheat your oven for at least 10-15 minutes before baking. Use an oven thermometer to verify actual temperature, as ovens can be off by 25°F or more.

Frequently Asked Questions

What is 350°F in Celsius?

350°F equals approximately 175°C (or 180°C rounded). This is the most common baking temperature for cakes, cookies, and many other baked goods. It's equivalent to Gas Mark 4.

What is Gas Mark 6 in Fahrenheit?

Gas Mark 6 equals approximately 400°F or 200°C. This is considered a "hot" oven temperature, suitable for roasting vegetables, baking bread, and cooking pizza.

How do I convert Celsius to Fahrenheit for baking?

To convert Celsius to Fahrenheit: multiply by 9/5 and add 32. Formula: °F = (°C × 9/5) + 32. For example, 180°C = (180 × 9/5) + 32 = 356°F ≈ 350°F.

Why do British recipes use Gas Marks?

Gas Marks were developed in the UK when gas ovens became popular in the early 20th century. The numbered scale made it easy to communicate temperatures before digital displays. Many traditional British recipes still use this scale.

Should I use fan/convection settings?

Fan-assisted or convection ovens cook about 25°F (15°C) hotter than conventional ovens. Reduce temperature by 25°F or shorten cooking time by about 10-15% when using fan settings.

What temperature should I bake at if a recipe says "moderate oven"?

A "moderate oven" typically means 350°F (175°C) or Gas Mark 4. This is the most common baking temperature and is suitable for most cakes, cookies, and casseroles.
