American recipes and fan ovens
US recipes give conventional oven temperatures in Fahrenheit. In a UK fan oven, convert 500°F to 260°C first, then take off 20°C to get 240°C.
What cooks at 500°F
500°F is hotter than most gas ovens go, so use gas mark 9 and give the oven longer to heat up. The nearest other setting is gas mark 8 (230°C, 450°F).

Common questions
What gas mark is 500°F?
Hotter than gas mark 9, the top setting on most gas ovens.
What is 500°F in Celsius?
260°C exactly, which recipe charts round to 260°C.
What is 500°F in a fan oven?
240°C. Convert to Celsius, then take 20°C off for the fan.
Sources and assumptions
- Conventional means an electric oven with the fan off. Fan settings are 20°C lower.
- Recipe charts round temperatures to the nearest 10°C or 25°F, so exact conversions differ by a few degrees.
