Oven Temperature for Baking: Celsius and Fahrenheit
Convert oven settings between Celsius and Fahrenheit, understand fan-assisted adjustments, and keep recipes reliable across regions.
Recipes travel; oven dials do not
A US cookie recipe at 350 °F is not the same sentence as a European recipe at 180 °C—even when those temperatures are the intended conversion pair. Writers round, ovens run hot or cold, and fan modes change heat transfer.
Start with a correct Celsius ↔ Fahrenheit conversion, then adjust for your oven’s behaviour. An oven thermometer is more valuable than a third significant digit on a website.
Temperature conversion is affine (scale plus offset), not a simple multiply. That is why “divide by two” folklore fails. Use a proper converter or the exact formulas.
Fan (convection) vs conventional
Fan-assisted ovens often need a lower set point than conventional recipes assume. Many bakers reduce by about 20 °C (roughly 25–40 °F) when switching to fan—check your oven manual.
Convert the printed recipe temperature first, then apply the fan adjustment. Do not mix the steps or you will double-correct.
Air-fryers and toaster ovens have different thermal mass. Treat their charts as separate; still convert units carefully when a recipe only lists one scale.
Candy, meat, and probe temperatures
Candy stages and meat doneness are often quoted in Fahrenheit in older US books and in Celsius elsewhere. Convert the target probe temperature the same way you convert oven set points—then verify with a calibrated thermometer.
Carryover cooking means food temperature rises after removal. Unit conversion does not change that physics; timing and resting still matter.
Kelvin is rarely printed on consumer recipes but appears in science-of-cooking texts. Knowing that a 1 °C change equals a 1 K change helps when reading those charts.
A simple baking workflow
Identify the recipe’s scale. Convert to your oven’s scale. Adjust for fan if needed. Preheat fully. Confirm with an oven thermometer on the rack you will use.
Write both °C and °F on a sticky note for family recipes you reuse. Dual labels prevent weekend arguments and burnt trays.
When sharing recipes online, include both scales. Your international readers should not have to guess which “gas mark” culture you meant.

Frequently asked questions
What is 350 °F in Celsius?
350 °F converts to about 177 °C, commonly rounded to 180 °C in home recipes. Confirm with your oven and recipe style.
Do I convert differently for fan ovens?
Convert the printed temperature first, then apply your oven’s recommended fan reduction. Conversion and fan adjustment are separate steps.
Why did my cake still burn after converting correctly?
Ovens vary. Rack position, pan colour, and calibration errors matter as much as the unit label. Use an oven thermometer.
