Oven Temperature Converter

Convert a recipe temperature

1. Select the oven mode and °C or °F already stated in the recipe, then enter its temperature. Choose the mode and unit you want to use as the target.
2. If the modes differ, choose a 20°C difference, a 25°F difference or a custom difference from your recipe or appliance instructions. The two presets are not equivalent.
3. Read the target setpoint together with its adjustment. Check whether your recipe already lists fan settings or your oven automatically converts a conventional entry before making another adjustment.

Units and oven assumptions are different

To convert an absolute temperature, multiply Celsius by 9/5 and add 32 to obtain Fahrenheit. To convert a temperature difference, multiply by 9/5 without adding 32. A 20°C difference is therefore 36°F, not 25°F.

This tool subtracts your selected difference when moving from conventional to fan cooking, and adds it for the reverse direction. When both modes match, it changes only the unit and ignores any retained adjustment draft.

A recipe chart may round 350°F to 180°C. Exact unit arithmetic gives about 176.7°C instead. This converter does not round through a chart or snap its result to your oven's available dial settings.

The supported range is 50–300°C, or 122–572°F, for both the source and the unrounded target. Results show at most one decimal place. These limits and display digits describe the calculator, not an oven's accuracy or safe operating range.

Three worked conversions

For 180°C conventional, choose a 20°C difference and a fan target. The result is 160°C, equivalent to 320°F. Reversing those modes with the same difference gives 180°C conventional.

For 350°F conventional with a 25°F difference, the fan target is 325°F, about 162.8°C. Choosing a 20°C difference instead gives 314°F, about 156.7°C. Neither choice is automatically correct for every recipe.

For 180°C conventional to conventional in Fahrenheit, the result is 356°F. No oven-mode adjustment is applied, even when a fan-adjustment choice remains saved in the page.

Check the recipe and appliance

Fan behavior and automatic conversion depend on the appliance and selected function. Do not apply a manual reduction on top of settings that have already been adjusted. Read the recipe and appliance instructions rather than treating this arithmetic as a tested cooking recommendation.

This tool does not convert gas marks, cooking times, broil or grill settings, steam, microwave or air-fryer programs. It does not determine doneness or food-safety temperatures, calibrate a thermostat or guarantee an equivalent bake.
