One chart for every recipe
Recipes travel, and their temperatures come in Fahrenheit, Celsius, or gas marks depending on where they were written. This converter and its reference chart let you follow any of them without second-guessing the dial — type a number, pick the scale, and read off the rest.

❓ Frequently Asked Questions
How do I convert Fahrenheit to Celsius?
Subtract 32 and multiply by 5/9. For example, 350°F becomes (350 − 32) × 5/9 ≈ 177°C. To go the other way, multiply Celsius by 9/5 and add 32. The tool does both directions instantly as you type.
What are gas marks?
Gas marks are the numbered settings on UK and some European gas ovens. Gas mark 4 is roughly 350°F / 180°C — a moderate oven — with each step up adding about 25°F. The reference chart on this page lines up every gas mark with its Fahrenheit and Celsius equivalent.
Why don't the chart temperatures convert exactly?
Oven and gas-mark charts are rounded to convenient dial numbers — 180°C is listed as 350°F even though the exact conversion is a couple of degrees off. That rounding is standard in recipes and makes no practical difference to cooking.
Can I use this for air fryer temperatures?
Yes. Air fryers use the same Fahrenheit and Celsius scales as ovens. If you're adapting an oven recipe, convert the temperature here, then use the Oven to Air Fryer Recipe Converter to lower it for the basket.
