Oven Temperature Converter
An oven temperature converter translates cooking temperatures between Fahrenheit, Celsius, British Gas Marks, and fan-forced convection ovens. It incorporates the standard culinary rule of reducing conventional temperatures by 20°C (25°F) for fan ovens, showing that a standard 350°F recipe corresponds to 177°C conventional, 160°C fan, or Gas Mark 4.

How Does the Oven Temp Calculator Work?
- Choose your source unit: Fahrenheit (°F), Celsius (°C), Gas Mark, or Fan-Forced.
- Enter the temperature from your recipe or select one of the quick baking presets.
- Instantly view the converted settings across all 4 oven scales plus the culinary heat category (e.g. Slow, Moderate, Hot).
What Is the Oven Temp Formula?
Convert between thermal units and apply the standard 20°C / 25°F convection reduction for fan-forced ovens.
How Do You Calculate Oven Temp Step by Step?
Converting 350°F standard recipe for a fan-assisted convection ovenConventional Celsius: (350 - 32) × 5/9 = 176.7°C (Gas Mark 4)
Apply Fan Convection rule (subtract 20°C / 25°F): 176.7°C - 20°C = 156.7°C (approx 160°C Fan) or 325°F Fan
Culinary heat range: Moderate baking temperature
