Charts use conventional dial settings rather than exact arithmetic — 180 °C is published as 350 °F even though the exact conversion is 356 °F. The difference does not matter in an oven.
Questions
- Why is 180 °C given as 350 °F when the arithmetic says 356?
- Recipes and oven dials use conventional round settings rather than exact conversions. Every published chart pairs 180 °C with 350 °F, and the small difference has no practical effect on cooking.
- Do I need to change the temperature for a fan oven?
- Yes. A fan circulates hot air, so it cooks faster at the same dial setting. The usual rule is to reduce a conventional-oven recipe by 20 °C.
