140°C in Fahrenheit
The exact conversion plus the fan oven and gas mark equivalents, since almost every recipe assumes a conventional oven.
140 degrees Celsius is
284 °F
In a fan or convection oven use 120 °C.
The formula
Multiply by 9/5 and add 32.
(140 × 9 ÷ 5) + 32 = 252 + 32 = 284 °F
Oven settings at this temperature
| Setting | Value |
|---|---|
| Conventional oven | 140 °C |
| Fan / convection oven | 120 °C |
| Fahrenheit | 284 °F |
| Gas mark | Between marks |
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 140°C in Fahrenheit?
284°F. Multiply the Celsius figure by 9/5 and add 32.
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.
