Common questions
What is 350°F in Celsius?
350°F is 177°C, commonly rounded to 180°C in recipes, which is Gas Mark 4.
Is Gas Mark the same across all ovens?
Gas Mark is a UK standard and isn't a precise linear scale like Fahrenheit or Celsius — the table above gives the standard conversion, but always check your specific oven's manual if it lists Gas Mark settings.
Does fan/convection oven temperature need adjusting?
Yes — fan (convection) ovens typically run about 20°C (25°F) hotter than a conventional oven at the same setting. Reduce the temperature by that amount, or check your oven's manual for its specific fan adjustment.
