400 usually means 200 in some American ovens..
752 F
A 350 degree Fahrenheit oven is approximately 177 degrees Celsius.
It would depend on the degree thermostat installed, probably 195 degrees F.
Pierce each potato in several places to prevent them from exploding while baking. Preheat the oven to 400 F, place the potatoes on an oven rack or a baking sheet in the oven, and bake them for about 45 to 60 minutes, until tender when tested with a thin skewer.
About 2 hrs. How to roast it (to be ready at 12:00): 09:11 turn on oven to 475°F 09:41, cover with foil and place in oven and reduce the heat to 400°F. Remove foil at 11:20 Out of oven at 11:45 Rest for 15 minutes Carve at 12:00 Have a look at http://www.cookipedia.co.uk/wiki/index.php/Meat_cooking_time_calculator
400 deg F = 204.44.. deg C
400°F is equal to 204.4°C.
Most breads are cooked at 350-400 degrees F; the higher the temperature, the crustier and faster the outside will bake.
To bake uncooked meatballs in the oven, preheat the oven to 400°F (200°C) and cook them for about 20 to 25 minutes. Ensure they reach an internal temperature of 165°F (74°C) for safe consumption. Cooking times may vary slightly based on the size of the meatballs, so it's a good idea to check them for doneness.
Degrees F = Degrees C * 1.8 + 32 So, 140C = 284F. If you are converting a recipe, in the US this would probably be a 300 degree oven.
350 degrees for almost all cakes if not, 400 degrees
For temperature times with a fan oven, you need to subtract about 10 degrees from the conventional oven time given. So, for 160 degrees F in a conventional oven, you would set a fan oven at 150 degrees F.
