Oven & fan temperature converter
Apply your chosen fan-oven adjustment in Celsius or Fahrenheit.
A clear answer. Here’s how.
Subtracts your chosen Celsius offset for conventional-to-fan conversion, or adds it for the reverse. Converts Fahrenheit through Celsius first. The default 20°C is an editable cooking convention, not a universal appliance rule; follow the recipe and oven manufacturer’s guidance.
