Pro Tip: Oven Thermometers

Most home ovens are off by 25-50°F! The dial is rarely accurate. An inexpensive hanging oven thermometer is the best investment for better baking results.

Oven Temperature Conversion Chart & Calculator

Finding an old British recipe that calls for "Gas Mark 4" or a European one using Celsius? Don't let conversion confusion burn your biscuits. Our Baking Temperature Converter instantly switches between Fahrenheit (°F), Celsius (°C), and Gas Marks. It also calculates the adjustment needed for modern Fan / Convection Ovens, which typically cook faster than conventional setting.

How to Convert Temperatures

  1. Enter Current Temp: Type the number you have into the Fahrenheit or Celsius box.
  2. Check Fan Adjustment: If you are using a Fan/Convection oven, use the "Fan Oven" value (usually 20-25°C lower).
  3. Gas Mark: The tool automatically finds the nearest Gas Mark setting for older ovens.
  4. Quick Reference:
    • 350°F = 180°C = Gas Mark 4 (Moderate)
    • 400°F = 200°C = Gas Mark 6 (Hot)
    • 300°F = 150°C = Gas Mark 2 (Slow)

Frequently Asked Questions

What is the difference for Fan ovens?

Fan (Convection) ovens blow hot air around the food, cooking it faster and more evenly. You generally need to reduce the temperature by 25°F (20°C) to match a conventional oven recipe.

Why does my oven burn everything?

Oven dials are often inaccurate. Your "350°F" setting might actually be 375°F. We highly recommend buying an inexpensive oven thermometer to hang inside so you know the real temperature.

What is Gas Mark?

Gas Mark is a scale used on gas ovens in the UK and Ireland. It adjusts the gas flow to regulate heat. Gas Mark 1 is roughly 275°F (Cool), while Gas Mark 8 is 450°F (Very Hot).
