Fan (convection) ovens
A fan oven circulates hot air, so it cooks faster and more evenly. Set it about 20 °C lower than a recipe written for a conventional oven (25 °F lower in Fahrenheit), or keep the temperature and shorten the time by about a quarter. Most Indian OTGs (oven-toaster-grills) without a fan count as conventional ovens. Convection microwaves in convection mode behave like fan ovens.
Recipes round temperatures: 180 °C is exactly 356 °F, but recipes write 350 °F, and 200 °C (392 °F) is written 400 °F. The converter shows both the exact value and the usual recipe value.
Frequently asked questions
What is 180 °C in Fahrenheit?
356 °F exactly, written as 350 °F (Gas Mark 4) in recipes. In a fan oven, use 160 °C.
What is 350 °F in Celsius?
177 °C exactly, usually rounded to 180 °C for a conventional oven or 160 °C for a fan oven.
What gas mark is 200 °C?
Gas Mark 6 (400 °F), which is a hot oven.
