What 140°C is used for
Cool oven
140°C is Gas Mark 1. It is a slow oven, used for long, gentle cooking such as slow-roast pork shoulder or rich fruit cakes that bake for several hours.
Typical uses at this heat: slow roasts, pavlova, rich fruit cake.
Not sure your oven really reaches 140°C? Many ovens run hotter or cooler than the dial. See how to check your oven’s temperature.
How to convert 140°C to °F
Multiply by 9, divide by 5, then add 32:
252 + 32 = 284°F
The quick “double it and add 30” trick gives 310°F, which is 26°F too high at this temperature. That’s fine for weather but not for baking, so use the exact figure.
