A US oven setting
A 350 °F recipe becomes about 177 °C for a metric oven dial.

A US recipe calling for 350 °F converts to about 176.7 °C. Most ovens cannot be set that precisely, so 175 °C or 180 °C is the practical dial setting; fan-assisted ovens may also require the recipe maker's separate adjustment.

Browse all general convertersAbout Fahrenheit to Celsius
Fahrenheit is the temperature scale of the United States - weather, ovens, thermostats - but the rest of the world, and all of science, reads Celsius. Converting Fahrenheit to Celsius turns an American temperature into the metric figure everyone else uses. The formula subtracts thirty-two and multiplies by five-ninths, so a 100 °F fever is about 37.8 °C and a 350 °F oven is a familiar 177 °C to a metric cook. US recipes and thermostats are the usual reasons: an oven dial or a slow-cooker setting in Fahrenheit has to become Celsius before a metric appliance can match it. Meat-safety and candy-making temperatures from US cooking sites convert to Celsius so a metric probe thermometer can hit the same target. A Fahrenheit temperature difference needs only the scale factor, not the offset used for an actual temperature reading.
Using Fahrenheit to Celsius
- Type a number of degrees. You can paste a value with its unit; the tool reads the number.
- The exact factor is applied and the result is shown as °C, updating live as you type.
- Copy the answer, or switch to the reverse converter to go from °C back to °F.
Where fahrenheit to celsius helps
Both directions

Convert the number before choosing a setting
Subtract 32 from a Fahrenheit reading before multiplying by 5/9. For 212 F, the calculation is (212 - 32) x 5/9 = 100 C; multiplying first would give a different answer. An oven dial may only offer five- or ten-degree increments, so round after converting. Fan-assisted settings and equipment calibration are separate adjustments and are not part of this unit conversion.
Before you use the result
- The result is rounded for readability, so a value converted and then converted back may differ in the last decimal place. The underlying factor is exact.
- Units in your input are ignored - only the number is read - so make sure the figure you type is really in °F.
Questions about Fahrenheit to Celsius
What is 98.6 °F in Celsius?
98.6 Fahrenheit - normal body temperature - is 37 Celsius. A reading of 100.4 °F, a common fever threshold, is 38 °C.
