240°C in Fahrenheit
The exact conversion plus the fan oven and gas mark equivalents, since almost every recipe assumes a conventional oven.
240 degrees Celsius is
464 °F
In a fan or convection oven use 220 °C, which is gas mark 9.
The formula
Multiply by 9/5 and add 32.
(240 × 9 ÷ 5) + 32 = 432 + 32 = 464 °F
Oven settings at this temperature
| Setting | Value |
|---|---|
| Conventional oven | 240 °C |
| Fan / convection oven | 220 °C |
| Fahrenheit | 464 °F |
| Gas mark | 9 |
Fan ovens circulate air, which transfers heat faster, so recipes written for a conventional oven need about 20 °C less. Doing both that and shortening the time will undercook the dish.

Frequently asked questions
What is 240°C in Fahrenheit?
464°F. Multiply the Celsius figure by 9/5 and add 32.
What gas mark is 240°C?
Gas mark 9. In a fan oven, use 220 °C.
What is the formula?
°F = (°C × 9/5) + 32. To go the other way, °C = (°F − 32) × 5/9.
At what temperature are the two scales equal?
−40. That is the single point where Celsius and Fahrenheit give the same number, which makes it a handy check on any conversion you do by hand.
