How to Use the Cooking Time & Temperature Converter

Enter the recipe's original temperature and cooking time, then select the new target temperature (or oven type, like convection) — the tool estimates an adjusted cooking time, which should be treated as a starting estimate to check against actual doneness rather than a guaranteed exact endpoint.

The Cooking Time & Temperature Converter estimates the needed time adjustment — here's how to use it and why checking doneness still matters.

Entering the original recipe details

Enter the original temperature and time, and the new target temperature — the tool applies a standard adjustment estimate, similar in principle to the guideline covered in the temperature-adjustment guide.

Treating the result as a starting estimate

As covered in the underdone-dish guide, checking actual doneness (a thermometer for meat, a toothpick test for baked goods) rather than relying purely on the adjusted time estimate remains the reliable way to confirm a dish is actually finished.

Frequently asked questions

Does this tool account for convection ovens specifically?

Check whether the specific tool includes a convection adjustment option, following the guideline covered in the convection-vs-conventional guide — if not, applying that adjustment manually alongside the tool's base temperature conversion covers it.

Can I use this for adjusting a recipe to an air fryer instead of a regular oven?

For an air fryer specifically, the Air Fryer Converter is built for that particular adjustment, which tends to be more significant than a standard convection adjustment given how compact and efficient air fryer heating typically is.
