Continuous conversions use °C ≈ gas × 14 + 121; the table is the common rounded reference (Gas 1 = 275°F … Gas 9 = 475°F).

What is this tool?

Recipes may list Fahrenheit, Celsius, or gas mark. Convection/fan ovens often cook hotter in practice — many cooks reduce conventional settings by about 25°F (≈20°C). Always check your oven manual.

How to use it

  1. Enter a temperature in °F, °C, or gas mark.
  2. Read the converted values.
  3. Optionally apply the convection adjustment tip for fan ovens.
