Oven Temperature Converter
Quick answer: 350°F is about 177°C or gas mark 4; for a fan or convection oven, lower the setting by roughly 20°C (25°F).
Fahrenheit, Celsius and gas mark — all at once — plus a fan/convection adjustment so your bake isn't 20 degrees too hot.

How it works
Fahrenheit and Celsius are exact conversions (°C = (°F − 32) × 5⁄9), while gas marks map to the nearest standard setting. Fan or convection ovens circulate air and run hotter, so switching fan on also drops the dial by about 20 °C / 25 °F. Ovens vary more than you'd think, so an inexpensive oven thermometer is the surest way to bake consistently.
Frequently asked
What does the fan adjustment do?
Fan (convection) ovens circulate air and cook hotter, so we drop the temperature about 20°C / 25°F from the conventional setting.
What is a gas mark?
It's the dial scale on UK gas ovens. Gas mark 4 is the everyday baking temperature, roughly 180°C or 350°F.
Should I trust my oven dial?
Not entirely — many run hot or cold. An inexpensive oven thermometer is the surest way to bake consistently.
Why do my bakes brown too fast?
Often the oven runs hot, or you're using a fan setting without lowering the temperature. Drop about 20 °C for fan ovens and check with a thermometer.
What temperature is a “moderate” oven?
Recipes that say 'moderate' usually mean around 350 °F / 180 °C — gas mark 4.
