How to convert Fahrenheit to Celsius (formula)
To convert Fahrenheit to Celsius, subtract 32 from the given degree in Fahrenheit and multiply by .5556. You can also multiply by five and divide by nine.
| Example: (80 F -32) X .5556 = 26.7 C |
How to convert Celsius to Fahrenheit (formula)
To convert Celsius to Fahrenheit, multiply the temperature by 1.8 and add 32 to the given degree in Celsius. You can also multiply the given number by nine, divide by five and then add 32 to convert the degrees of Celsius to Fahrenheit.
| Example: (30 C x 1.8) + 32 = 86 F |

How do you convert cooking times to different temperatures?
You convert cooking times to different temperatures by accounting for the percentage difference between the temperatures. Once you figure out the percentage difference, multiply the initial cooking time by it. It’s also important to factor in some wiggle room to make sure you don’t ruin your favorite recipe, like these old-fashioned sugar cookies.
| Example: Start temperature is 400 F or 200 C with a 60-minute cooking time, and you want to increase the temperature to 450 F or 230 C. Divide 400 by 450 to get the percentage difference of 0.89, or 89%. You will then take the initial cooking time of 60 minutes at 400 F, or 200 C, and multiply it by 0.89 to get 53 minutes. |
Tips for accurate oven temperature conversions
Achieving the perfect bake or roast often depends on precise oven temperature; even a small difference in temperature can affect your dish. Here are some tips to ensure your oven is set to the correct temperature every time:
- Regularly calibrate your oven to ensure it’s heating to the correct temperature. This simple step can make a big difference in your cooking results.
- Invest in a high-quality probe thermometer to accurately measure the internal temperature of your dishes, especially for meats.
- Identify any hot spots in your oven by placing slices of bread on a baking sheet and seeing where they toast fastest — adjust your cooking strategy accordingly.
- Always allow your oven to preheat fully before placing your dish inside to ensure even cooking from the start.
You can also use an oven thermometer. Place it inside to verify the temperature, as built-in oven dials can sometimes be inaccurate.

400 F in the oven converts to 205 C.
Yes, 350 F converts to 180 C and 180 C converts to 350 F.
Cooking something at 350 instead of 400 generally means you need to increase the cooking time by 20%-25%, though the exact time will depend on the type of dish and its size. A good rule of thumb is to add five to 10 minutes for every 30 minutes of cooking time, but always check for doneness by using a food thermometer or following visual cues like color and texture.
Oven temperatures are typically categorized into three levels: low, medium and high. Low temperatures range from 200 to 300 and are ideal for slow cooking or braising. Medium temperatures, between 325 and 375, are perfect for baking most dishes. High temperatures, 400 and above, are best for roasting, broiling and quick cooking methods like flash baking.
